{"version":"1.0","type":"rich","title":"Let's make a bar chart with D3.js!","description":"A bar chart maps country populations from a CSV file to horizontal rectangles. The chart uses D3 v5’s `scaleLinear` and `scaleBand` to position and size bars, with population values multiplied by 1,000 and rendered as SVG `rect` elements. Data loading relies on `d3.csv`, and the layout is fixed at 960 by 500 pixels. The example focuses on the fundamental steps of binding data to SVG shapes and encoding values through a linear scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/49c6768256fb4b84b0c8af3bb939d77e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
