Stacked Bar Chart for World Population
This stacked bar chart visualizes the religious composition of the world's 20 most populous countries in 2010, using data from the Pew Research Center's Global Religious Landscape report. Each horizontal bar represents a country, segmented by religion, with population values in millions. Hovering over a color legend highlights the corresponding religious group across all countries while fading the others. The visualization is built with D3.js, utilizing `scaleOrdinal` for colors, `stack` for segmenting bars, and a custom `colorLegend` function for interactive filtering.
