Hi,
 
Is there any datasets of 2 dimensional datapoints (each datapoint is a vector of two values (x,y)) following different distributions and forms ? Or is there any codes to generate such a datapoints ? I want to use them to plot/visualise how some clustering algorithms performs on them. Here are some examples:
