{"version":"1.0","type":"rich","title":"Untitled","description":"This chart visualizes the popularity of research topics over time using a stacked area chart with a silhouette offset. The visualization uses d3.layout.stack, d3.svg.area, and d3.time.scale to render SVG paths with cardinal interpolation, while d3.svg.axis displays the x and y axes. Interactive features include tooltips on mouseover that show topic values, hover highlighting that dims other layers, and a vertical guide line that follows the cursor. Data comes from a comma-separated CSV file loaded with d3.csv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1fd90b31041448fa9b586c70e54986e7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
