{"version":"1.0","type":"rich","title":"Activity_6 Task 1","description":"This example shows a horizontal bar chart of the top 30 countries by 2020 population, with the y-axis listing country names and the x-axis displaying population values in billions. Built with React and D3 v5, it uses `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis, rendering SVG rectangles via the `Marks` component. The data is loaded asynchronously from a CSV file using `d3.csv`, and axis ticks are generated with `xScale.ticks()`, formatted with the `d3.format` SI prefix to abbreviate large numbers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6ade4e9548544a3583fc42452bee7e02?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
