A smooth and area-preserving flattened map was subsequently constructed by deforming the ALS map using the proposed algorithm that combines the density-equalizing map and the reference map techniques. ...
The initial map was generated by a previously described arc-length scaling (ALS) mapping method, which projects a 3D carotid surface onto a 2D non-convex L-shaped domain. ...

In this work, we propose a novel method called the volumetric density-equalizing reference map (VDERM) for computing density-equalizing map for volumetric domains. ...
The density-equalizing map, a technique developed for cartogram creation, has been widely applied to data visualization but only for 2D applications. ...
Therefore, the accuracy of the density-equalizing reference map can be improved by increasing the resolution of the numerical domain. ...
