{"version":"1.0","type":"rich","title":"activity 6_question 2","description":"This example visualizes daily transaction counts for multiple stores as a stacked bar chart. It shows how each store contributes to the total transactions on each date between January 1 and January 5, 2013. The chart uses D3 v6 to load CSV data, group records by date and store number, and stack the values with `d3.stack()`. It renders SVG rectangles with scales for positioning and colors from `d3.schemeCategory10`, alongside axes and a legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/228bd8d3e161450987e200c686fda991?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
