To animate this, it’s very simple. All we need to create is another function (in this case update_points) that will define what changes at every frame of the animation. I’ve defined my function to adjust the size of every circle according to the timestep/frame, as well as change th...
In my actual application I have 1000s of frames to deal with, with several custom settings on different figures plus dpi on save().2 x faster withFigure()is a significant issue for large datasets to animate from. I hope now it is more clear why my query. I'm just trying to understan...
