{"version":"1.0","type":"rich","title":"[A7] (Small Multiples of Lines Chart with a Color Legend)","description":"This example uses small multiples to display the Consumer Price Index (CPI) of four grains—Corn, Rice, Rye, and Wheat—from 2000 to 2015, with each grain in its own line chart. A color legend identifies each grain’s stroke color. The code loads CSV data via `d3.csv`, renders SVG line charts using `d3.line` and `d3.axisBottom`, and builds the legend with `d3.legendColor` from the d3-legend library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1fbc0f711a734d64b5a9dae1f8627907?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
