{"version":"1.0","type":"rich","title":"T8-Q1","description":"This example displays a horizontal bar chart of population data for 30 countries in 2020, using D3 v5 within a React framework to render SVG elements. Bars are colored green, with a blue axis line and formatted tick labels that abbreviate large numbers (e.g., “B” for billions). The code builds scales with `d3.scaleBand` and `d3.scaleLinear`, computes the domain from the CSV data, and uses React components for axes and marks. Data is fetched from a GitHub-hosted CSV file and processed by the `useData` hook.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2023e5bb38ed416cb19a021ba0219975?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
