I have an excel file that contains 485k rows x 3 columns of integer values. Sample data:
cluster.x cluster.y cluster.z 1 3 3 3 1 4 4 2 5 ...
I did a kmeans clustering with 6 clusters, but I am figuring out what is the best way to display the result. I plotted it using plot3d() as shown below, but it is hard to differentiate different clusters since the values are all integers.
Does anyone have any suggestions? If possible, I also want it to be able to visualise how many data points there are in each cluster (e.g a bubble plot where the size of the bubble depicts the number of data points).
