{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays a week of temperature readings from multiple cities around the world, with each city represented by a distinct colored line plotted over time. The visualization uses D3 v6 with SVG rendering, employing `d3.scaleTime`, `d3.scaleLinear`, `d3.line` with `curveBasis`, and `d3.nest` to group data by city. A color legend built with `d3.scaleOrdinal` and `schemeCategory10` identifies each line. The data comes from a CSV file loaded via `d3.csv` and rendered with custom axes, grid lines, and a title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/20053d7ecea446f9b26d7310a624c215?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
