{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays one week of temperature data from cities worldwide, sourced from Data Canvas - Sense Your City. Each line represents a city, color-coded using `d3.scaleOrdinal` with `schemeCategory10`, and plotted over time with `d3.scaleTime` and `d3.scaleLinear`. The visualization uses `d3.line` with `curveBasis` for smooth curves, `d3.nest` to group data by city, and a custom `colorLegend` function rendered as SVG. Axes are created via `d3.axisBottom` and `d3.axisLeft`, with gridlines and a title, all styled through the SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/531ecf75fc1f4deab4654861232e654d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
