{"version":"1.0","type":"rich","title":"multi charts","description":"This example presents two SVG charts built with D3.js v7, both visualizing daily sales trends for three series (A, B, C) from `sales_trends.csv`. The top chart displays multi-series line plots, while the bottom combines bars for series A and B with an overlaid line for series C. The code uses `d3.csv` with `d3.autoType` for data loading, `d3.scaleTime` and `d3.scaleLinear` for axes, and renders interactive tooltips styled via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1103a832c5ce457092a50a14569ae96e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
