{"version":"1.0","type":"rich","title":"area chart","description":"An animated SVG area chart depicts yearly cost data from a CSV file, loading via D3's `d3.csv` fetch and rendering with an SVG `path`. The chart maps time-based `year` values on a time scale and `cost` on a linear scale, using `d3.area` to generate the filled region. Interactive red circles, added via `svg.selectAll('dot').data(data).enter()`, display a tooltip on mouseover with the year and cost, while the tooltip div transitions its opacity using D3's `.transition()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/60f31e6306284d0c9ec787f1dc593bad?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
