What does the graph of this field looks like?

Question

A Field is given by $\frac{x}{\left(x^{2}+y^{2}\right)}\hat i+\frac{y}{\left(x^{2}+y^{2}\right)}\hat j$ where $\hat i$ $\hat j$ are unit vectors along $x$ and $y$ axis respectively. How would graph of this field would look like on the cartesian coordinate system.
