Regarding missing some of the crimes, we actually didn’t miss any of the sales of crack (cocaine base), meth, or heroin. The ones that you see that we didn’t select may have been possession offenses (we were only interested in sales) or cocaine offenses (as opposed to crack).

Additionally, we do have text filters that you can use to type in valid values, although I wouldn’t argue that that would be more accurate than selecting them individually from the list in our example (this would entirely depend on the type and volume of data).

You missed many of the cocaine, meth, heroin crimes when you selected them in the video.

What you need is a text filter which you can apply to the descriptions. Selecting by hand (like you did) is slow and error-prone.

Hey – this is really cool.

You should come to our Data Camp event which is on November 7th. We are having a Data SF Web App contest.

Either way – keep up this kind of stuff – it’s awesome!
