{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays one week of temperature data in degrees Celsius for cities worldwide, sourced from the Data Canvas - Sense Your City initiative. It shows multiple colored lines tracking temperature over time, with a color legend identifying each city. The visualization uses D3 v5 with d3.scaleTime, d3.scaleLinear, d3.scaleOrdinal, d3.line with curveBasis smoothing, d3.nest for grouping, and d3.axisLeft/axisBottom. SVG rendering with mix-blend-mode creates overlapping line effects, while axis labels and a title are added via SVG text elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f73d8a61df594062b57f76cb2d734e2e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
