A simple Xcode, Cocoa, Mac OS X app/utility to draw rectangles on a 2D XY canvas, like a scatter plot.
The rectangles will be positioned via XY coordinates and filled with colors from a data table in a text file.
I want to be able to do the following interactively from the UI:
Select a data file (i.e., from the standard tool bar)
Adjust the X & Y dimensions of the rectangles via sliders
Set the background color of the canvas
initiate a plot via a button
This will be one component of a larger project.
