Scatter pie plot
问题 I'm trying to visualize a soft clustering. There are a number of points and a small number of clusters, each point belongs to each cluster with some probability. Currently, I'm overlaying a scatterplot for each cluster, with the size of 'o' markers varying by the probability. This allows easy identification of the most probable cluster, but not much beyond that. I'd like to draw a scatterplot of pie charts, i.e. one small pie chart for each of the many data points, showing these probabilities
