WorldTrade is a weighted undirected graph whose nodes are 80 countries and edges are trading amount between the countries. The visualization was created with the following steps:

1. load worldtrade.mat; % load the network: 'A' weighted adjacency matrix, 'C' class labels (continents).
2. Y=wtsne_p(A,false); % run weighted t-SNE, without over-attraction initialilzation
3. DisplayVisualization(Y,C); % show the scatter plot, colors indicating continents

After getting the 2-D coordinates, we can supply them to graphviz to draw the graph with the country names, where the node size is proportional to the square root of its degree.
