{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"A multi-line chart displays a week of temperature readings across multiple cities, with time on the x-axis and temperature on the y-axis. The visualization uses d3.scaleTime, d3.scaleLinear, and d3.scaleOrdinal with a category10 color scheme to encode city identity. Lines are generated with d3.line and a basis curve, while a custom color legend component renders SVG circles and text. Data comes from a CSV file loaded via d3.csv, with axes and gridlines produced by d3.axisBottom and d3.axisLeft.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a1a07f2ed8064c4d85317ad86129e8d8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
