The orange observed series and teal synthetic series draw themselves over two seconds using `transition.attrTween` with `stroke-dasharray` in D3 v7. An SVG grid, axes, and title appear with fade-in transitions. Data comes from a master's thesis on synthetic control methodology for special economic zones.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8d43df679b2f402c8bb58a73fb80939a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
