Visualize list of calls in csv file to learn max # of simultaneous calls

bigbangtech used Ask the Experts™
I have a csv file with a list of telephone calls, with columns for start time, end time, and duration for 30 days. I need to figure out how calls overlapped, to see what was the highest amount of simultaneous calls, and average amount of simultaneous calls by day, and for the month.
