{"version":"1.0","type":"rich","title":"D3 init","description":"A minimal bar chart maps country populations from a CSV file to SVG rectangles. The code loads `data.csv` using `d3.csv`, multiplies each population value by 1000, and renders horizontal bars with `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the y-axis. It appends rectangles to an SVG element selected via `d3.select`, with dimensions derived from the scales and a fixed margin offset. The example demonstrates a basic D3 v5 data-joining workflow with asynchronous data loading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0d7f5a6534194d989d44af05c72c0e0b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
