{"version":"1.0","type":"rich","title":"activity 6 tutorial 1","description":"This example presents a horizontal bar chart of the 2020 population for 30 countries, sorted from largest to smallest by the y-axis. The data is loaded from a CSV file via `d3.csv` and rendered as SVG rectangles using React components. It applies `d3.scaleBand` for the categorical y-axis and `d3.scaleLinear` for the numeric x-axis, with `d3.format` to abbreviate population values in billions. Axes and marks are built with reusable React components that map data to SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5ea26f71cf1d49d896b7dfcfecd53cba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
