1000 points in 10s
This looks fancy but it's one line of code in GeoGebra, see if you can make it. Once done you can easily draw the potential wells and hills for any number of point charges.

- make one coordinate of the dots vary according to the inverse of the distance from the origin
- make another coordinate equal to some variable, a
- turn on trace
- vary a with a slider
