{"version":"1.0","type":"rich","title":"Sobrerrepresentación en el sistema electoral español (2015-2019)","description":"A continuous-area cartogram compares the 2015–2019 Spanish general election results across the 52 provincial constituencies. The area of each province is scaled inversely to the number of votes needed to elect a representative, highlighting overrepresentation of national parties. Color intensity encodes the proportion of seats won by the selected party relative to the total for national parties. Animated transitions animate between elections and parties. Built with D3 v4 using SVG, the visualization uses a composite projection of Spain and lets users explore how district magnitudes distort electoral weight. Nationalist and regional parties are excluded from the analysis.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-2b8eb65eb5e3b6420ca1e67aec93ddef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
