{"version":"1.0","type":"rich","title":"Making a Bar Chart","description":"This example demonstrates the initial step of building a bar chart with D3.js, binding population data from a CSV file to SVG rectangles. The code uses `d3.csv` to load data and `selectAll` with data joins to append `<rect>` elements, though it only sets fixed width and height attributes without scaling or axes. The visualization currently renders placeholder rectangles, showing the foundation for a chart rather than a polished result.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/33ac223211704d14972c35d6516c88ea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
