{"version":"1.0","type":"rich","title":"Activity6_population","description":"This example shows a horizontal bar chart of country populations in 2020, using a band scale for countries and a linear scale for population values. The chart is rendered as SVG with React components, using D3 v5 utilities such as `scaleBand`, `scaleLinear`, `max`, and `format`. Population values are formatted with SI prefixes, converting gigabytes to billions, and each bar includes a native SVG tooltip. The data is loaded via a custom hook (`useData`) from a CSV source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dfe5d0afaffa41459485e0a06909275a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
