{"version":"1.0","type":"rich","title":"D3 Line Chart with Multiple Lines","description":"This visualization displays temperature trends for multiple cities over time, with a color-coded line for each city and a legend identifying each series. The chart uses a time-scaled x-axis, a linear temperature axis, and a categorical color scale. Built with D3 v5, it employs `scaleTime`, `scaleLinear`, `scaleOrdinal`, and `axisBottom`/`axisLeft` to construct axes. Data is loaded from an external CSV containing city temperature readings, then nested by city using `nest()`, with lines rendered as SVG paths using `lineGenerator` and a basis curve.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eda08c0fddb245bb9265f4d251b7e483?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
