{"version":"1.0","type":"rich","title":"Making a barchart","description":"This bar chart displays population totals for five countries, with rectangles sized according to each nation’s population value. The visualization uses D3 v6 APIs including `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to load data from a CSV file, map values to positions, and render axes. The SVG chart applies a steelblue fill to bars, with margins and a padded band scale for categorical spacing. Data is parsed from strings to numbers before rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c3100ec0b4a64c5e881b3781bec01be6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
