{"version":"1.0","type":"rich","title":"Asssignement","description":"A bar chart displays monthly sales for 100 coffee shop branches, with each bar colored on a sequential blue scale to encode sales magnitude. Using D3 v7 within a React component, the visualization loads data from a CSV file via `d3.csv`, aggregates it, and renders SVG rectangles scaled with `scaleBand` and `scaleLinear`. Branch labels are rotated on the x-axis, and axes are drawn with `axisBottom` and `axisLeft`, with hover effects changing bar color to orange.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c9e0ebcab11341cda7b7250544b497cf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
