{"version":"1.0","type":"rich","title":"Making A Bar Chart","description":"A bar chart displays population data for ten countries, encoded as a sequence of SVG rectangles. The chart uses D3 v5 to load a CSV file with `d3.csv`, parse the population values, and bind the data to SVG `<rect>` elements via D3's `selectAll('rect').data()` join. The visualization renders at a fixed 960 by 500 pixel SVG canvas without additional layout or axis logic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8522393d3a4143c385691e6d7ff3cd0c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
