Background
In some project, the dataset I analyzed is a bunch of features for different areas (countries or provinces). Presenting those data in bar-chart or choropleth-plot on the map is an essential work.
In the website Our world in data, I found some great works for visualizing the dataset like the example below.
This web app contains the following functions:
- variations of the data by the time series (from 1990-2016)
- Change the data feature (i.e. population, GDP among the countries worldwide)
- Easily for saving and sharing.
I have known about the plot.ly package, which has the similar functions.
Question
I want to build a web-based tool for visualizing geo-data in bar/bubble plot (examples in Fig.2) using Python.
How to implement this function? Any advice/examples would be appreciated.
