{"version":"1.0","type":"rich","title":"D3 Multi Line Chart","description":"This interactive D3 multi-line chart compares U.S. foreign assistance dollars across five global regions, with a radio-button toggle switching between economic and military aid datasets. The visualization plots yearly spending trends using colored lines, with axes formatted in millions and a hover tooltip for details. Built with React and SVG, it uses d3.csv to load remote data, d3.scaleOrdinal for region colors, d3.line with curveBasis for smooth paths, and transition.attrTween-style animation (via transition().duration()) when toggling datasets, updating the line geometry accordingly.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b4b21972304844e69255678ee38670cc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
