{"version":"1.0","type":"rich","title":"multiple-to-stack","description":"This example shows how individual time-series lines for “Impressions” and “Clicks” can be converted into a stacked area chart using D3 v4. The SVG visualization reads monthly data from a CSV file, parsing date and numeric values, then renders the two categories as stacked areas. The stacked layout is computed with d3.stack, and the chart includes an x-axis for time, a y-axis for values, and a color-coded legend distinguishing the two series.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-81c08c5c0cb3fc0a8af4b6f2dcea3227?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
