 With *LightningChart* you can create different types of charts for various use-cases. Previous tutorials have demonstrated how to create simple 2D charts with multiple line-series and axes, area-series and bar-series. In this tutorial, we will show how to create a Simple 2D Heat Map using *IntensityGridSeries*.

 A Heat Map is a matrix containing individual values which are presented as colors. In data visualization, Heat Maps can be utilized to provide visual content and feedback about data values through variations in coloring. For this tutorial, we recommend you create a new WinForms or WPF application. *LightningChart* offers two methods for creating Heat Maps - *IntensityGridSeries* and *IntensityMeshSeries*. *IntensityGrid* is evenly-spaced, rectangular series in X and Y space which allows visualization of M x N array of nodes. *IntensityMesh* is similar to the *IntensityGrid*, but in *IntensityMesh*, series does not need to be rectangular, while series nodes can be positioned arbitrarily in the X and Y space. For this tutorial, we are using the *IntensityGridSeries*.
