Creative way to display table with multiple columns and rows in a grid

[zero66]

I have a matrix of user data points, userid, selection, selection result. Now, I can have any number of users (average would be 15-50) and any number of selections (average would be 14-20).I want to display back to the user their selection, if it was correct or not as well as all of the other users' selections and whether they too got it correct or not. That way they can see how they did as well as how they did compared to anyone else.I was thinking a large grid; however, that would probably require some sort of horizontal scroll bar regardless is the users are columns or rows.I am assuming that there is no "good" way to display such a large grid on a page (HTML5). Is there? Any interesting examples?Can someone suggest a more creative way to display this data? Maybe, the rows are the selections and the user is the first column...and then let him select what other users he wants to compare too? Thoughts? Examples?Thanks
