{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This visualization displays temperature readings for multiple cities over a one-week period, with each city represented by a colored line. The chart uses D3 v5’s `scaleTime` and `scaleLinear` for axes, `line` with `curveBasis` for smooth paths, and `nest` to group data by city. A color legend, built from `scaleOrdinal` with `schemeCategory10`, identifies each line. The SVG rendering includes axis labels, a title, and grid lines. Data comes from a CSV file loaded via D3’s `csv` function, with timestamps parsed as dates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/57fe48febca94af29201071c13bc27a8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
