Currently, it doesn't have a whole lot of features, but I'll be adding more in the future. Here's currently what it can do:
- Graph an equation (duh).
- There are currently some rendering issues with asymptotes which will be focused on at some point.
- Integrate and derive equations.
- Graph a slope field of a `dy/dx =` style equation.
- View a tangent line of an equation.
- Display a vertical bar graph.

graph.Graph(new Equation(x => Math.Pow(2, x))

Color = Color.Green,

});
