{"version":"1.0","type":"rich","title":"Activity 6_Task 1","description":"This horizontal bar chart visualizes the 2020 populations of 30 countries. Built with React and rendered as SVG, it uses D3’s `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis. The `Marks` component draws rectangles whose widths correspond to population values, with tooltips formatted via D3’s `format` function. Axis tick labels are formatted with the `.2s` specifier to show values in billions, and data is loaded from a remote CSV using D3’s `csv` function within a custom `useData` hook.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1bb369731c084117888299aa4ff50b4f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
