Bar graph of United States I can input data to?

I need a Map of the US showing the 50 states and the ability to insert a number and it plop down a "bar" like a bar chart.



I am an attorney and we have clients in many states across the US. I'd like to "dumb" down the data for the partners to basically be able to show them how concentrated our clientele base is for hearings/etc.



Anyone know of such a thing? Link?
