It uses Vega-Lite APIs to build layered line, rule, and text marks, with interactive selection via `vl.selectSingle()`. Data is loaded asynchronously from a CSV via d3’s `csv` function, filtered to selected regions and series. The chart is rendered with Vega’s SVG renderer, and a guide title and labels are customized through the config object.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c242c68b52dd42388c0d035c118d5550?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
