D3 Example
This interactive stacked bar chart visualizes the distribution of religious populations across different countries, using horizontal bars segmented by religion. The visualization leverages D3.js, with d3.layout.stack to create the stacked segments and d3.scale.ordinal for country positioning. Hovering over a country brings up a tooltip displaying the specific religion and population value, while hovering over the color legend dims unrelated segments. The chart uses an SVG rendering approach with a responsive axis and custom legend, drawing from the included religion survey dataset.
