{"version":"1.0","type":"rich","title":"Barchart Tutorial","description":"This example shows a horizontal bar chart of amounts per person, with red bars scaled linearly along the x-axis and categorical names on a band scale along the y-axis. The visualization renders as SVG using D3 v5, loading data from a local CSV file via `d3.csv` and converting the numeric amounts with `+d.amounts`. Scales, axes, and rectangles are created with `d3.scaleLinear`, `d3.scaleBand`, `d3.axisLeft`, and `selection.enter().append('rect')`, with margins applied through a group transform.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/90bce557c1e3481db20d6d281d54989e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
