{"version":"1.0","type":"rich","title":"Making a bar chart","description":"This example shows a bar chart where each data row from a CSV file is represented as a fixed 300-by-300 pixel rectangle, though no bar height or x-position mapping is applied. The code loads data with `d3.csv`, converts the `population` field to a number, and appends SVG `rect` elements using `selectAll` and `enter`. It uses `d3.select` for SVG selection and `d3.scaleLinear` (imported but not used), with data rendered as static squares rather than proportional bars.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d9810fba908b4879aeeddcb440b2731b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
