{"version":"1.0","type":"rich","title":"Untitled","description":"This interactive line chart compares daily high temperatures in New York, San Francisco, and Austin, with each city rendered as a steel-blue path. The chart uses D3.js v3 with `d3.time.scale` for the date axis and `d3.scale.linear` for the temperature axis, while `d3.interval` and `d3.svg.line` draw the smoothed curves. The data is embedded as a tab-separated string, parsed via `d3.tsv.parse`, and colors are assigned using `d3.scale.category10()`. A legend and mouse-over effects are included to highlight the selected city's values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0453591e8f6d4de296e90f01a9155840?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
