q2
A stacked bar chart displays the estimated 2010 religion breakdown for the 20 most populous countries, using data from the Pew Research Global Religious Landscape. Built with D3.js, the visualization uses `d3.layout.stack()` for the stacked bars and `d3.legend.color()` for the color legend. Hovering over bars triggers tooltips via `d3-tip`, while hovering over legend entries highlights individual religions by applying a semi-transparent overlay and re-rendering foreground bars. The chart is rendered as an animated SVG.
