{"version":"1.0","type":"rich","title":"D3 Line Chart with Multiple Lines","description":"This visualization displays city temperature trends over time as a multi-series line chart titled “Temp Around the World.” It plots temperature readings (y-axis) against timestamps (x-axis) for multiple cities, with each city distinguished by color from a categorical color scale. Built with D3 v5, the chart uses `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.lineGenerator` with `d3.curveBasis` for smoothed paths, `d3.nest` to group data by city, and a custom legend component. The interactive SVG renders the data from a CSV file sourced from data-canvas-sense-your-city-one-week.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ea82ac0c5b88457199756c8c245f0b75?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
