{"version":"1.0","type":"rich","title":"Line chart with multiple lines","description":"A line chart displays a week of temperature readings for multiple cities, with each city represented by a colored line and a legend identifying its color. The visualization uses D3.js scales and axes (d3.scaleTime, d3.scaleLinear, d3.axisLeft, d3.axisBottom) with a d3.line generator and curveBasis for smoothing. Data comes from a CSV file loaded via d3.csv, and city colors are assigned using d3.scaleOrdinal with schemeCategory10. The chart is rendered as SVG with grid lines and labeled axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/10793f34c5dd4a2b9298af73608ebb0d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
