spatial region

I have created simple dataset which consists of 4 types of data such as data1,data2,data3,data4 for various years. I used the punchccard chart over hear to represent the data for the respective years.And size of each bubble varies with value associated to it.

Channels used: Identity channel (spatial region)
Marks : bubbles.
