Fork of Religions of Largest 20 Countries
This stacked bar chart visualizes the estimated 2010 religion breakdown of the world’s 20 most populous countries, using data from the Pew Research Global Religious Landscape. It shows the proportion of each religion within each country as horizontal stacked bars. Hovering over a bar displays a tooltip with the exact population count, while hovering over the color legend highlights that religion across all countries. The visualization uses D3.js to implement scales, axes, and the `d3.layout.stack` algorithm, along with `d3.legend` for the interactive color key and `d3.tip` for tooltips.
