{"version":"1.0","type":"rich","title":"Canadian Exports to US Treemap","description":"This visualization displays Canada's exports to the United States in 2022 as a hierarchical treemap, with rectangles sized by export value and colored by sector (e.g., Minerals, Agriculture). Hovering over a product rectangle highlights related items and reveals a tooltip with the product name, export amount, share, code, and sector. Built with D3.js, it uses d3.treemap for layout, d3.scaleOrdinal for color assignment, d3.scaleSqrt for font sizing, and a ResizeObserver for responsive dimensions. The data loads from a TSV file via d3.tsv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a4ff1337d9e04b0a98c0b4a8db8d4018?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
