{"version":"1.0","type":"rich","title":"Multi-series chart","description":"This multi-series line chart visualizes e-commerce performance trends over time, plotting three metrics—visitors, orders placed, and revenue in USD—across a 30-day period. Using d3.csvParse to load external CSV data, the visualization applies d3.curveCatmullRom for smooth line interpolation and d3.axisBottom/axisLeft for axes. Separate colored paths (steelblue, green, red) represent each metric, accompanied by a legend and gridlines generated via d3.axisLeft with tick sizing. The SVG rendering uses D3’s scaleLinear for x/y domains and appends title and axis labels dynamically.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/44ad946680944249ab24621020a17462?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
