My previous post was unclear. I'll try again. It shouldn't take a 70 line Ruby script or indeed procedural programming to generate a CSV file from a MongoDB database. So Lazy web :-) what's the best Best MongoDB to CSV tool to generate CSV files for graphing using one of the JS toolkits, Excel, etc so I don't have to write a 70 line Ruby script like getOneDayAnswerRate.rb?
tyranny of tools
In my not so humble opinion generating a graph like this from a database shouldn't require a 70 line ruby script!
