{"version":"1.0","type":"rich","title":"Testing grouped barchart","description":"This visualization shows a partially implemented grouped bar chart. It attempts to display population data from a CSV file using D3 v5. The implementation uses `d3.csv` to load data, `d3.scaleBand` for the x-axis, and `d3.scaleLinear` for the y-axis. A second `d3.scaleBand` handles subgroup positioning, and `d3.scaleOrdinal` defines the color palette. The chart is rendered as an SVG using `d3.axisBottom` and `d3.axisLeft`. The code references an external data file, but the actual data loading does not match the expected grouping structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/07d7440693c34e29899ab59520fca852?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
