{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"The visualization displays a week of temperature readings for San Francisco as a multi-line chart, with the y-axis labeled \"temperature\" and the x-axis representing time hourly. It uses D3 v5’s `d3.line` with `curveBasis` to draw each city’s temperature path, grouped by `d3.nest` and colored via `scaleOrdinal` with `schemeCategory10`. The SVG includes axes with `axisLeft` and `axisBottom`, a title, and a color legend built from a custom `colorLegend` component. Data comes from a semicolon-delimited CSV file, and rendering is entirely in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/feb792a94d4b4b71abc587649072b415?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
