{"version":"1.0","type":"rich","title":"Untitled","description":"This example shows a small multiple chart with one line chart per data group, where each group represents a category from a CSV file and displays its numeric trend over time. The visualization is built with D3.js v4 and renders SVG graphics. The code uses `d3.nest()` to group data by category, `d3.line()` to draw each line, and `d3.axisBottom` and `d3.axisLeft` for axes. Colors are assigned via `d3.scaleOrdinal`, and each small chart is labeled with its group name.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/16ab646f3d4040d2b48e4fba8fc68e61?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
