{"version":"1.0","type":"rich","title":"Activity 6 task 2","description":"This visualization shows the petal length distribution for three flower species (setosa, versicolor, and virginica) using a stacked bar chart. The horizontal bars display combined petal length values for each species. Built with D3.js v7, it uses `d3.stack()`, `d3.scaleLinear()`, `d3.scaleBand()`, and `d3.axisBottom()` to render SVG, with color encoding via `d3.scaleOrdinal()`. Interactive mouseover tooltips display exact petal lengths. The data originates from the iris dataset CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7274c742e4824de6880d79f933752e35?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
