QuerySketchQuerySketch is a prototype program for querying a database of stock price information using a sketching interface. Many users have a target graph in mind when they look for new investments--for instance, they may wish to diversify their portfolio by finding a stock that has historically moved in the opposite direction from their current holdings. This interface is designed to be a simple, easy and flexible method for formulating graph-centric queries.
Here are some screenshots:
Ready to query: The user will draw on top of the graph to formulate a query.
After a query: The target is represented by the thick black line; matching companies are shown with thumbnail graphs
