{"version":"1.0","type":"rich","title":"Question1","description":"This example displays a stacked bar chart of population by country, segmented by religion, with an interactive color legend that highlights corresponding chart segments on hover. It loads data from a CSV file and uses D3 v5 APIs including `scaleOrdinal`, `schemeCategory10`, and `select`, while relying on `observeResize` from `@curran/responsive-axes` for responsive sizing. The visualization is built through local ES6 modules that separate the chart, legend, and data-parsing logic, with population values converted to millions for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/60f4aa8e699749b69d458669b67c0856?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
