{"version":"1.0","type":"rich","title":"d3 mouseover multi-line chart","description":"This interactive multi-line chart displays temperature readings for New York, San Francisco, and Austin over a two-week period. The visualization uses D3 v3 to render an SVG with smooth basis-interpolated lines, a time-scaled x-axis, and a linear y-axis showing temperature in Fahrenheit. Each city has a distinct color from the category10 scale, with a legend and end-of-line labels. The code includes a mouse-over effect that draws a vertical tracking line, using the d3.svg.line and d3.time.scale APIs to follow the cursor across the plotted data.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-444f11166ce952a6d46f89b7f2913caa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
