{"version":"1.0","type":"rich","title":"Line Chart With Multiple Lines","description":"This example visualizes San Francisco temperatures over time for multiple cities using a multi-line chart. The visualization employs D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisLeft`, and `axisBottom` to construct the axes and scales. Data is loaded from a CSV file and grouped by city using `nest`, then each line is rendered via the `line` generator with `curveBasis` smoothing. The SVG render includes gridlines, a rotated y-axis label, and a title, all styled through CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/36ba643af6d74d269e24caf21c7db136?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
