Fork of Religions of Largest 20 Countries
This interactive stacked bar chart visualizes the estimated 2010 religious breakdown of the world’s 20 most populous countries, with data from the Pew Research Global Religious Landscape. The code uses D3.js (version 3.5.5) with the `d3.layout.stack` and `d3.nest` APIs to create the stacked layers, while axes and legends are built with `d3.svg.axis` and `d3.legend.color`. Hovering over any bar displays a tooltip via the `d3-tip` library showing the country, religion, and population count. The legend is also interactive: hovering over a religion name highlights that religion’s bars across all countries by rendering a semi-transparent overlay and a foreground layer of subset bars.
