Made some more updates, the numbers now have decimal notations for easy reading. I have made the axis of the graph auto adjust to the values, this will give some more definition to the graph on lower peak concurrency. I also removed the times from the bottom of the graph. Lastly I added a Peak concurrency record indicator, which you don't see now but will when there is a record concurrency.
I have the daily graph now in a state where I like it, but I'm open to any ideas or suggestions.
A future plan, is linking this graph to a page that has more statistics on Second Life and other virtual worlds.
