started a new class for generating clouds of words. Previously only had clusters so there could be only 1 cluster of words. A cloud is a collection of these clusters, nicely spaced out.
created a new class to generate word clouds. Previously the code could make clusters which is a single collection of words. The cloud class will divide the words into clusters and display them all.
created word cloud with basic algorithm for placing satellite clusters but there's still overlap and the axes need to resize to fit the whole cloud.
