Chapter 13 d3.js Intereactive Choropleth Map

Heather Zhu

There are many practical tools to make visualizations. In addition to using R as we learned in class, D3.js is a JavaScript library for producing dynamic, interactive data visualizations in web browsers.

I uploaded an example of creating an interactive choropleth map using D3.js and geojson in this GitHub Page.
Here’s the rendered interactive map on heroku.
To make the code easier to understand, I created a walkthrough video tutorial.
