A Sankey diagram visualizes the early spread of a virus, using SVG paths to show the flow of transmission between countries. Node rectangles are colored by country, and link thickness encodes the relative number of cases transferred. The layout is computed with a custom `d3.sankey` module, which uses functions like `computeNodeDepths`, `relaxLeftToRight`, and `computeLinkDepths` to position nodes and routes. Links are drawn with cubic Bézier curves via the `link()` method, and nodes are draggable using `d3.drag()`.
AI-generated descriptionThis visualisation was implemented to show the rate of spread between countries in the early stages of the outbreak. as we can see in the sankey diagram.
From analysis we can see that the provinces china were the carriers of the virus to the rest of the world. which led to secondary travel to new places such as europe and australia to spread it further. to parts of America and Africa.
