{"version":"1.0","type":"rich","title":"Đồ Án Thực Hành ","description":"This visualization presents a multi-question analysis of supermarket sales data, beginning with a bar chart that displays the average customer rating for each city (Yangon, Naypyitaw, and Mandalay). The D3.js v4 code loads data from CSV files, including `supermarket_sales.csv` and `city.csv`, and uses `d3.nest()` and `d3.mean()` to aggregate ratings. Interactive mouseover events change bar colors and display values, while SVG text elements label the chart axes. The entire layout is constructed using D3 selections and scales within a React framework.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ff18294983724d948e38d54c31825b7c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
