{"version":"1.0","type":"rich","title":"Multi-line Chart","description":"This multi-line chart displays monthly average temperatures (in °F) for four U.S. cities—New York, Los Angeles, Chicago, and Houston—using a distinct colored line for each, plus tooltips on hover. The D3 v7 code loads and parses a CSV dataset from a GitHub gist, then renders the lines and interactive circles as SVG within a React-compatible HTML page. The chart uses linear scaling for the y-axis (10–90°F) and a band scale for months, with user interactions handled directly via mouseover events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e50dab81cf0e4d25b23a8b64f9043978?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
