{"version":"1.0","type":"rich","title":"Activity 7","description":"A horizontal bar chart displays population figures for 2020, with country names on the y-axis and numerical values on the x-axis. Built with React and D3 v5, the visualization uses `d3.scaleBand` for the categorical axis, `d3.scaleLinear` for the quantitative axis, and SVG rendering. Data is loaded asynchronously via a custom `useData` hook, and tick labels are formatted using `d3.format`. Axis components and marks are separated into modular React components for clarity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9852645f0196407ab1a3832c1090036c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
