{"version":"1.0","type":"rich","title":"fresh block","description":"A multi-line chart displays temperature readings for several cities over time, parsed from a tab-separated data file with `d3.tsv` and `d3.timeParse`. The code uses `d3.scaleTime`, `d3.scaleLinear`, and `d3.scaleOrdinal` with `d3.schemeCategory10` to map dates, temperatures, and city colors, while `d3.line` with `d3.curveBasis` draws smoothed paths. Axis labels and city names appear via `d3.axisBottom`, `d3.axisLeft`, and SVG text elements. The visualization renders entirely as SVG, with each city’s series and its final value labeled at the line’s endpoint.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-fb00860e087bbd370b7b5ff36f4f1c81?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
