Field of a dipole

About

🎯 Visualization of electric dipole field
🧠 Inspired by 7_Dipole.py
🐍 A VPython demo is available as well, see dipole_field.py
👉 Electric dipole field formula:

$$\overrightarrow{E} ( \overrightarrow{r} ) = -\frac {1} {4\pi\epsilon_0} \nabla \bigg( \frac{\overrightarrow{r} \cdot \overrightarrow{p}} {r^3} \bigg),\quad \overrightarrow{p} = q(\overrightarrow{r}_+) -q(\overrightarrow{r}_-)$$
