{"version":"1.0","type":"rich","title":"charts","description":"This example visualizes monthly sales trends from a CSV data source, comparing three product lines from 2019 to 2023. It shows a multi-series line chart with time-scale axes, using D3 v7 and SVG rendering. The code loads data with `d3.csv`, maps dates via `d3.timeParse`, and draws lines with `d3.line`, alongside a legend and axis labels. The second part combines a bar chart for total sales with an overlaid line for average price, using a dual y-axis scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4a0a43da3651494392af4de4c49c5e73?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
