Evaluation

This section provides results on computational time comparison and a
usability study to evaluate the efficiency of Angular Treemaps .

Computational time comparison

Java 1.6 with Eclipse Platform was used to develop the prototype. The
program was executed using an ordinary personal computer with AMD
Phenom 2.1 Ghz and 2GB of RAM. Table 5.1 illustrates the computational
times for the algorithm's tessellation process on a variety of data sets,
excluding the time for file reading, rendering, and displaying.
