{"version":"1.0","type":"rich","title":"textured area chart","description":"A stacked area chart uses the Textures library to fill each series with a distinct pattern—circles, lines, and crosses—instead of solid colors, applied via `textures.circles()`, `textures.lines()`, and `textures.paths()`. Built with React and D3 v4, it loads CSV data, nests it by year, and stacks three groups using `d3.stack()`. The SVG paths are drawn with `d3.area()`, with each layer’s fill set to the corresponding texture’s URL from a `d3.scaleOrdinal` palette, creating a visually separated multi-series comparison over time.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9b651ccf87254adba27a4469dedae917?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
