{"version":"1.0","type":"rich","title":"D3 Course 1: Bar Chart","description":"This example shows a bar chart comparing population totals for ten countries, drawn as an SVG with a linear scale for population and a band scale for country names. The render function builds axes, labels, and rectangular bars using D3 v5 APIs including `scaleLinear`, `scaleBand`, `axisBottom`, `axisLeft`, and `selectAll`/`enter`. It loads data from a local CSV file via `d3.csv`, multiplies each population value by 1000, and displays the result with formatted tick labels. The chart includes a title, axis labels, and a steel-blue fill for each bar.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f9e1a9e6213147c9998d83bd7a6f6a79?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
