{"version":"1.0","type":"rich","title":"d3 mouseover multi-line chart","description":"An interactive multi-line chart displays temperature readings for New York, San Francisco, and Austin over time, with each city represented by a distinct colored line and legend. The visualization uses D3 v3 to render SVG elements, including axes, lines, and text labels, while parsing tab-separated data via `d3.tsv.parse`. Mouseover effects, implemented with D3 event handlers, highlight the closest data point and display a vertical guide line, enhancing comparison across the three series.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-f88eefc1e9980d7174390d38d742fed6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
