   <p>About: This visualization is for the Project 1 of the course H517 Visualization Design, Analysis & Evaluation. The data for the project is provided by the instructor. The visualization for the project is done by me. The Map shows the Cholera Epidemic at London in 1854. Jon Snow created a similar map to identify the source of the Cholera epidemic. </p>
