{"version":"1.0","type":"rich","title":"Bar Chart","description":"This bar chart visualizes population data from a CSV file, mapping each country’s population value to a rectangle. The code uses D3 v7’s `csv` loader, `scaleLinear`, and `max` functions to process the data, converting population values to numbers and multiplying by 1,000. It renders fixed-size 300x300 SVG rectangles, which do not yet encode the data proportionally—a partial implementation of the chart. The React-free example relies on selecting an SVG element and appending rects via `selectAll` and `enter`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7b357efc4b82499aafd1a3eaa80c4d1c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
