{"version":"1.0","type":"rich","title":"Untitled","description":"A multi-line chart displays temperature readings for New York, San Francisco, and Austin over several days in October 2011, using D3.js v3 with SVG rendering. The visualization uses `d3.time.scale` for the x-axis, `d3.scale.linear` for temperature, and `d3.svg.line` with basis interpolation to draw smooth curves. It colors each city's line via `d3.scale.category10`, adds a legend, and includes a mouse-over effect with a vertical guide line. Data is parsed from tab-separated text using `d3.tsv.parse`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4f1a1e988717428bb81613b5c997e23d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
