{"version":"1.0","type":"rich","title":"Task8_Activity2","description":"This example visualizes the distribution of petal lengths across three Iris species using a stacked bar chart with tooltips. The code loads data from a local CSV file and renders the chart as SVG using D3 v7. It employs `d3.stack()` to create stacked segments, `d3.scaleBand()` for the categorical species axis, and `d3.scaleLinear()` for the continuous petal length axis. Interactive mouseover events display tooltips showing the exact petal length for each species and segment.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/065d7359535c4c448fd7458c1aa95ed4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
