{"version":"1.0","type":"rich","title":"Multi-Series Line Chart interact","description":"This interactive multi-series line chart visualizes daily average temperatures for New York, San Francisco, and Austin over one year. It uses D3 v4 to load a TSV dataset, parse dates with d3.time.format, and encode time on the x-axis with a time scale and temperature on the y-axis with a linear scale. A categorical color scale distinguishes the three cities, each rendered as an SVG line path. The chart applies conventional margins, computes domains using d3.extent and d3.min/max, and displays axes with d3.svg.axis. Hovering over the chart animates the lines, highlighting the nearest city's temperature values for interactive exploration.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-e9d1774ae5a121b8f6f6b8bdaa012861?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
