{"version":"1.0","type":"rich","title":"Making Bar Chart","description":"This example visualizes the top 10 most populous countries as a basic bar chart with no axes or labels, using population data from the United Nations World Population Prospects 2019. It loads CSV data with `d3.csv` and renders SVG rectangles with React, where each bar’s width is scaled by `d3.scaleLinear` and its vertical position uses `d3.scaleBand`. The chart updates after a brief “Loading...” state, driven by React hooks like `useState` and `useEffect`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4d22cda63acf481dbfe2125399298d53?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
