{"version":"1.0","type":"rich","title":"Activity_6 task 1","description":"This example displays a horizontal bar chart ranking the populations of 30 countries for 2020, with country names on the y-axis and population values on the x-axis. The visualization uses React with D3 v5’s `scaleBand` and `scaleLinear` to position bars, while custom React components render the axes and marks as SVG rectangles. Population data comes from an external CSV file, formatted using D3’s `format` function to display values in billions. Hovering over any bar reveals its exact value through a native SVG `<title>` tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/abaf446b08a9409aac7697bc9f57e018?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
