{"version":"1.0","type":"rich","title":"Multi-Series Line Chart","description":"This multi-series line chart displays daily average temperatures for New York, San Francisco, and Austin over a year. The data is loaded from a TSV file using d3.tsv, with dates parsed via d3.time.format. The x-axis uses a time scale, the y-axis a linear scale, and colors are assigned using d3.scale.category10. Domains are computed with d3.extent, d3.min, and d3.max, while d3.keys extracts the city names from the data. The visualization renders SVG axes and line shapes, with conventional margins applied, to compare seasonal temperature trends across the three cities.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-f12ef988bcd8e43a04175135bad7f0f1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
