摘      要：Cartograms serve as representations of geographical and abstract data,employing a value-by-area mapping *** a variant of the Dorling cartogram,the Demers cartogram utilizes squares instead of circles to represent *** alternative approach allows for a more intuitive comparison of regions,utilizing screen space more ***,a drawback of the Dorling cartogram and its variants lies in the potential displacement of regions from their original positions,ultimately compromising legibility,readability,and *** tackle this limitation,we propose a novel hybrid cartogram layout algorithm that incorporates topological elements,such as rivers,into Demers *** presence of rivers significantly impacts both the layout and visual appearance of the *** a user study conducted on an Electronic Health Records(EHR)dataset,we evaluate the efficacy of the proposed hybrid layout *** obtained results illustrate that this approach successfully retains key aspects of the original cartogram while enhancing legibility,readability,and overall accuracy.
