This gist contains some notes on constructing a query for census and economic data from the [DataUSA.io](http://datausa.io/) site. This is a quick-start guide to their API; for in-depth documentation check out their [API documentation](https://github.com/DataUSA/datausa-api/wiki/Overview).
A great way to learn how to structure a query is to visit a specific datausa.io page and click on the "Options" button on top of any graph, then select "API" to see the query syntax that created the graph.

Tips & tricks for an effective app challenge demo / presentation
App Challenge Presentation: Tips & Tricks
The purpose of an app challenge demo or presentation is to succinctly present your work on a civic app or solution to a panel of judges. It is usually the culmination of days (or even weeks) of work, and may only be limited to a few minutes.
Here are a set of suggestions that can help make these few minutes in front of a judging panel as effective and impactful as possible.
Get ready
Prepare your presentation ahead of time - while judges may understand the desire to work on a project right up to the last minute, making sure your presentation is solid and tells a compelling story is as important as your project itself. Take the time to prepare slides or a similar visual presentation that can accompany your remarks to the judges.
