-Data Morph transforms an input dataset of 2D points into select shapes, while preserving the summary statistics to a given number of decimal points through simulated annealing. It is intended to be used as a teaching tool to illustrate the importance of data visualization (see the [Data Morph in the Classroom](https://github.com/stefmolin/data-morph/#data-morph-in-the-classroom) section for ideas).
