Naver-Sankey(val>20일 때 val=20)
This is a Sankey diagram that visualizes the early spread of COVID-19 between countries and continents, showing flow rates between source and target regions. The code uses d3.v5 and the custom sankey.js library to render the diagram as an SVG. Node colors are assigned via d3.scaleOrdinal with d3.schemeCategory10, and links use d3.sankey's link path generator. Data is loaded from a JSON file with d3.json, and node dragging is enabled with d3.drag, triggering sankey.relayout to update the paths.
