This stacked bar chart visualizes the estimated 2010 religious composition of the 20 most populous countries, using data from the Pew Research Center’s Global Religious Landscape. Horizontal bars are segmented by religion, with country names on the y-axis and population counts on the x-axis. Hovering over a bar segment reveals a tooltip with the exact population for that religion, while hovering over the color legend highlights that religion across all countries by fading the other segments. The visualization is rendered with SVG and uses d3.layout.stack, d3.svg.axis, and d3-tip for interactivity.
