{"version":"1.0","type":"rich","title":"Cities population dataset for ICE-5 assignment","description":"This example shows a multi-series chart comparing city population and density, with blue bars for population values and a red line for density. The visualization uses D3 v7 to load CSV data from a GitHub gist, then renders an SVG with dual y-axes: population on the left and density on the right. The code employs `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for both y scales, and `d3.line` to generate the density path. Rotated axis labels and a manual legend distinguish the two metrics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c5657417e4a946ac90f0ac8d6f0f9141?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
