To visualize a minimum spanning tree from an adjacency matrix, where node sizes are determined by a relative size and node colors are differentiated by categories you can follow these steps:
- Create graph object using the adjacency matrix.
- Use the ‘minspantree’ function to calculate the MST from the graph.
- Visualize the MST using ‘plot’ function, with custom node sizes and colors as shown in the code given below.
marketSizes = [10, 20, 15, 25, 30]; % Example market sizes
countries = [1, 2, 1, 2, 3]; % Example country codes
% Generate colors
colors = lines(max(countries));
nodeColors = colors(countries, :);
figure;
plot(MST, 'MarkerSize', marketSizes, 'NodeColor', nodeColors, 'Layout', 'force');
For more guidance, refer to the MATLAB Documentation for ‘graph’ and ‘minspantree’ functions:
