What will we cover
- You want to map data from an HTML table to an interactive map.
- The data is not clean and it is difficult to map data to countries, as they are often called different.
Step 1: Using Pandas to read the data
We will look at a table of data from wikipedia.org. In this example we will look at the data from average human heights by country.
Inspecting the first few columns you see a few issues already. There is some data missing and some countries are represented more than once.
To simplify our exercise we will only look at Average male height.
Let’s use pandas to read the content and inspect it. If you are new to pandas I can recommend the this post.
To read the content you can use the read_html(url) call from the pandas library. You need to instal lxml as well, see this post of details.
import pandas as pd
# The URL we will read our data from
url = 'https://en.wikipedia.org/wiki/Average_human_height_by_country'
# read_html returns a list of tables from the URL
tables = pd.read_html(url)
# The data is in the first table
table = tables[0]
print(table[:20])
Which will result in the following output.
Country/Region Average male height ... Year Source
0 Albania 174.0 cm (5 ft 8 1⁄2 in) ... 2008–2009 [11][12]
1 Argentina NaN ... 2004–2005 [13]
2 Argentina 174.46 cm (5 ft 8 1⁄2 in) ... 1998–2001 [14]
3 Armenia NaN ... 2005 [15]
4 Australia 175.6 cm (5 ft 9 in) ... 2011–2012 [16]
5 Austria 179 cm (5 ft 10 1⁄2 in) ... 2006 [17]
6 Azerbaijan 171.8 cm (5 ft 7 1⁄2 in) ... 2005 [18]
7 Bahrain 165.1 cm (5 ft 5 in) ... 2002 [19]
8 Bahrain 171.0 cm (5 ft 7 1⁄2 in) ... 2009 [20][21]
9 Bangladesh NaN ... 2007 [15]
10 Country/Region Average male height ... Year Source
11 Belgium 178.6 cm (5 ft 10 1⁄2 in) ... 2001 [22]
12 Benin NaN ... 2006 [15]
13 Bolivia NaN ... 2003 [15]
14 Bolivia 160.0 cm (5 ft 3 in) ... 1970 [23]
15 Bosnia and Herzegovina 183.9 cm (6 ft 0 in) ... 2014 [24]
16 Brazil 170.7 cm (5 ft 7 in) ... 2009 [25][26]
17 Brazil – Urban 173.5 cm (5 ft 8 1⁄2 in) ... 2009 [25]
18 Brazil – Rural 170.9 cm (5 ft 7 1⁄2 in) ... 2009 [25]
19 Bulgaria 175.2 cm (5 ft 9 in) ... 2010 [27]
Where you by inspection of line 10 see a line of input that needs to be cleaned.
Step 2: Some basic cleaning of the data
By inspection of the data you see that every 10 lines (or something) an line repeats the column names.
While this is practical if you inspect the data as a user, this seems to be annoying for us when we want to use the raw data.
Luckily this is easy to clean up using pandas.
import pandas as pd
# The URL we will read our data from
url = 'https://en.wikipedia.org/wiki/Average_human_height_by_country'
# read_html returns a list of tables from the URL
tables = pd.read_html(url)
# The data is in the first table
table = tables[0]
# To avoid writing it all the time
AVG_MH = 'Average male height'
# Remove duplicate rows with 'Average male height'
table = table.loc[table[AVG_MH] != AVG_MH].copy()
print(table[:20])
Where you can see the data is has cleaned up these columns.
Country/Region Average male height ... Year Source
0 Albania 174.0 cm (5 ft 8 1⁄2 in) ... 2008–2009 [11][12]
1 Argentina NaN ... 2004–2005 [13]
2 Argentina 174.46 cm (5 ft 8 1⁄2 in) ... 1998–2001 [14]
3 Armenia NaN ... 2005 [15]
4 Australia 175.6 cm (5 ft 9 in) ... 2011–2012 [16]
5 Austria 179 cm (5 ft 10 1⁄2 in) ... 2006 [17]
6 Azerbaijan 171.8 cm (5 ft 7 1⁄2 in) ... 2005 [18]
7 Bahrain 165.1 cm (5 ft 5 in) ... 2002 [19]
8 Bahrain 171.0 cm (5 ft 7 1⁄2 in) ... 2009 [20][21]
9 Bangladesh NaN ... 2007 [15]
11 Belgium 178.6 cm (5 ft 10 1⁄2 in) ... 2001 [22]
12 Benin NaN ... 2006 [15]
13 Bolivia NaN ... 2003 [15]
14 Bolivia 160.0 cm (5 ft 3 in) ... 1970 [23]
15 Bosnia and Herzegovina 183.9 cm (6 ft 0 in) ... 2014 [24]
16 Brazil 170.7 cm (5 ft 7 in) ... 2009 [25][26]
17 Brazil – Urban 173.5 cm (5 ft 8 1⁄2 in) ... 2009 [25]
18 Brazil – Rural 170.9 cm (5 ft 7 1⁄2 in) ... 2009 [25]
19 Bulgaria 175.2 cm (5 ft 9 in) ... 2010 [27]
20 Burkina Faso NaN ... 2003 [15]
Step 3: Convert data to floats
Inspecting the data that we need (Average male height) it is represented as a string with both the cm and ft/in figure. As I live in Denmark and we use the metric system and have never really understood any benefit of the US customary units (feel free to enlighten me).
Hence, we want to convert the strings in the column Average male height to a float representing the height in cm.
Notice, that some are NaN, while the rest are having the first number as the length in cm.
We can exploit that and convert it with a lambda function. If you are new to lambda functions you can see this tutorial.
import pandas as pd
import numpy as np
# The URL we will read our data from
url = 'https://en.wikipedia.org/wiki/Average_human_height_by_country'
# read_html returns a list of tables from the URL
tables = pd.read_html(url)
# The data is in the first table
table = tables[0]
# To avoid writing it all the time
AVG_MH = 'Average male height'
AMH_F = 'Aveage male height (float)'
# Remove duplicate rows with 'Average male height'
table = table.loc[table[AVG_MH] != AVG_MH].copy()
# Clean up data to have height in cm
table[AMH_F] = table.apply(lambda row: float(row[AVG_MH].split(' ')[0]) if row[AVG_MH] is not np.nan else np.nan,
axis=1)
print(table[:20])
Resulting in the following.
Country/Region ... Aveage male height (float)
0 Albania ... 174.00
1 Argentina ... NaN
2 Argentina ... 174.46
3 Armenia ... NaN
4 Australia ... 175.60
5 Austria ... 179.00
6 Azerbaijan ... 171.80
7 Bahrain ... 165.10
8 Bahrain ... 171.00
9 Bangladesh ... NaN
11 Belgium ... 178.60
12 Benin ... NaN
13 Bolivia ... NaN
14 Bolivia ... 160.00
15 Bosnia and Herzegovina ... 183.90
16 Brazil ... 170.70
17 Brazil – Urban ... 173.50
18 Brazil – Rural ... 170.90
19 Bulgaria ... 175.20
20 Burkina Faso ... NaN
Notice that np.nan is also a float and hence, the full column Average male height (float) are floats.
Step 4: Merge two sets of data with different representations of countries
To make the map in the end we will use the geopandas library, which has a nice low resolution dataset used to color countries. While the data by geopandas is represented as a DataFrame it is difficult to merge it as the DataFrame we have created from the htm_read call to pandas has varying names.
Example can be United States in the one we created and United States of America in the geopandas. Hence, we need some means to map them to the same representation.
For this purpose we can use the library pycountry.
Hence, applying that to both DataFrames we can merge them.
import pandas as pd
import numpy as np
import geopandas
import pycountry
# Helper function to map country names to alpha_3 representation - though some are not known by library
def lookup_country_code(country):
try:
return pycountry.countries.lookup(country).alpha_3
except LookupError:
return country
# The URL we will read our data from
url = 'https://en.wikipedia.org/wiki/Average_human_height_by_country'
# read_html returns a list of tables from the URL
tables = pd.read_html(url)
# The data is in the first table
table = tables[0]
# To avoid writing it all the time
AVG_MH = 'Average male height'
CR = 'Country/Region'
COUNTRY = 'Country'
AMH_F = 'Aveage male height (float)'
A3 = 'alpha3'
# Remove duplicate rows with 'Average male height'
table = table.loc[table[AVG_MH] != AVG_MH].copy()
# Clean up data to have height in cm
table[AMH_F] = table.apply(lambda row: float(row[AVG_MH].split(' ')[0]) if row[AVG_MH] is not np.nan else np.nan,
axis=1)
# Clean up the names if used a dash before
table[COUNTRY] = table.apply(
lambda row: row[CR].split(' – ')[0] if ' – ' in row[CR] else row[CR],
axis=1)
# Map the country name to the alpha3 representation
table[A3] = table.apply(lambda row: lookup_country_code(row[COUNTRY]), axis=1)
# Read the geopandas dataset
world = geopandas.read_file(geopandas.datasets.get_path('naturalearth_lowres'))
# Do the same mapping to alpha3
world[A3] = world.apply(lambda row: lookup_country_code(row['name']), axis=1)
# Merge the data
table = world.merge(table, how="left", left_on=[A3], right_on=[A3])
# Remove countries with no data
table = table.dropna(subset=[AMH_F])
# These lines are just used to get the full data
pd.set_option('display.max_rows', 300)
pd.set_option('display.max_columns', 50)
pd.set_option('display.width', 1000)
print(table)
Which will result in the following.

Also, notice that we also removed the rows, which has no Average male height.
Step 5: Create the map with our data
Now we have done all the hard work.
It is time to use folium to do the last piece of work.
Let’s put it all together.
import pandas as pd
import numpy as np
import folium
import geopandas
import pycountry
# Helper function to map country names to alpha_3 representation - though some are not known by library
def lookup_country_code(country):
try:
return pycountry.countries.lookup(country).alpha_3
except LookupError:
return country
# The URL we will read our data from
url = 'https://en.wikipedia.org/wiki/Average_human_height_by_country'
# read_html returns a list of tables from the URL
tables = pd.read_html(url)
# The data is in the first table
table = tables[0]
# To avoid writing it all the time
AVG_MH = 'Average male height'
CR = 'Country/Region'
COUNTRY = 'Country'
AMH_F = 'Aveage male height (float)'
A3 = 'alpha3'
# Remove duplicate rows with 'Average male height'
table = table.loc[table[AVG_MH] != AVG_MH].copy()
# Clean up data to have height in cm
table[AMH_F] = table.apply(lambda row: float(row[AVG_MH].split(' ')[0]) if row[AVG_MH] is not np.nan else np.nan,
axis=1)
# Clean up the names if used a dash before
table[COUNTRY] = table.apply(
lambda row: row[CR].split(' – ')[0] if ' – ' in row[CR] else row[CR],
axis=1)
# Map the country name to the alpha3 representation
table[A3] = table.apply(lambda row: lookup_country_code(row[COUNTRY]), axis=1)
# Read the geopandas dataset
world = geopandas.read_file(geopandas.datasets.get_path('naturalearth_lowres'))
# Do the same mapping to alpha3
world[A3] = world.apply(lambda row: lookup_country_code(row['name']), axis=1)
# Merge the data
table = world.merge(table, how="left", left_on=[A3], right_on=[A3])
# Remove countries with no data
table = table.dropna(subset=[AMH_F])
# Creating a map
my_map = folium.Map()
# Adding the data from our table
folium.Choropleth(
geo_data=table,
name='choropleth',
data=table,
columns=[A3, AMH_F],
key_on='feature.properties.alpha3',
fill_color='YlGn',
fill_opacity=0.7,
line_opacity=0.2,
legend_name='Male height'
).add_to(my_map)
# Save the map to an html file
my_map.save('height_map.html')
Which should result in a map like this you can use in your browser. Zoom in and out.
This is nice. Good job.
