Before we can visualize the data on the map, we need to prepare the data. The first thing we will do is create a new model that we can use for the prepared data. Let's set this up:

1. In the Models folder in the MeTracker project, create a new class called Point.
2. Add properties for Location, Count, and Heat, as shown in the following code:

namespace MeTracker.Models
{ 
    public class Point
    {
         public Location Location { get; set; }

1. In the MeTracker project, open the MainViewModel class.
2. Add a private field called points, which is of the List<Point> type.
3. Create a property called Points, which is of the List<Point> type.
