{"version":"1.0","type":"rich","title":"Activity6_Question2","description":"This example shows the revenue distribution of electric vehicle manufacturers from 2018 to 2021 using a stacked bar chart. The chart uses D3 v7 to load data from a CSV file and render SVG elements, with `d3.stack()` to create stacked series and `d3.scaleOrdinal()` for color mapping. Revenue values are displayed along a linear scale, while manufacturers are positioned on a band scale. The visualization includes axes, bold labels, and a legend to distinguish the four years.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/db991456e3cb4e8a8fac1fcb1dbf22a2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
