Storing a key-value pair in maps (Java / C++) and dictionaries (Python) does not guarantee the sorted order of the input. Hence we additionally need to sort the data to get the desired output which ...

Python implementation of the one-layer treemap layout algorithm. Expanded the original version by adding x and y alignment axes, so the tiled treemap can represent 4-D information.

This paper presents a new approach to the large graph layout problem, which quickly generates an effective layout. This new method proceeds by generating a clustering hierarchy for the graph, applying ...

Higher order Voronoi diagram is a popular way to model higher order information for complex decision making such as "what-if" analysis. Visualising higher order information for moving objects is a ...
