Plot data month-wise and month-wise

I would like to plot my data (Month,Region) into a format so that I can see the following (example):
"How many requests were there from "East","West","Central" Region in Sept. month".

"How many requests were there from "East","West","Central" Region in July. month".

I guess first I will need to convert the dates from M/D/Y format to just Month Name and then I need to group the data into region-wise.

I cannot figure a simple way to do it.

I have attached my excel file below.

Thanks
