{"version":"1.0","type":"rich","title":"Temperature in San Francisco (Line)","description":"A dropdown menu lets users select a country, and a line chart displays that country’s population over time. The visualization uses D3.js to parse CSV data, render SVG axes and paths, and animate transitions between selections. A categorical color scale from `d3-scale-chromatic` assigns a distinct stroke color to each country’s line, while `d3.scaleLinear` maps years and population values to coordinates. The interface updates the line via a `transition` when the selection changes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a77f675d4f054687ac6e5dcbcfacf33d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
