{"version":"1.0","type":"rich","title":"Activity 7","description":"A horizontal bar chart displays the populations of 20 countries for 2020, ranked by country name on the y-axis and population magnitude on the x-axis. Built with React and D3 v5, the visualization uses `scaleBand` for the categorical axis and `scaleLinear` for population values, with SVG `<rect>` elements rendering the bars. Data is loaded asynchronously via `d3.csv` from a GitHub-hosted CSV file, and axis ticks are formatted using `d3.format` to abbreviate large numbers (e.g., converting Giga to Billions). The code includes custom `AxisBottom` and `AxisLeft` components that generate SVG tick marks and labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d08fe6c529b74ce2bec8a9434d5c2b07?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
