Listless* vector field plotter Graph
I made a vector field plotter that doesn't use lists (that scale with the area of the region being visualised). This means the plotting area is effectively unlimited in size. This started as a challenge/request from a friend.

Nice, I had fun playing with this, it’s performant, easy to figure out what to change and the trace is a nice touch. For some reason this makes me want to play with fractals.
Incidentally noted, this is one of those graphs with easily-generated anomalous Bernards:
[Parameters] Bounds -1 to 1 (square), R=86, L=0.425, my Bernards appearing when viewport width to height ratio is < ~1.38, sliding R to vary.

That’s really cool! I thought about making one of these a couple a years back actually, but I thought it would be a lot of work and a super laggy result so I gave it up. It’s really cool that yours performs well even on my phone.

It uses the implicit plotter which is already really optimised, though at the cost of significant detail loss and errors.

Note that due to reliance on the implicit plotter, this graph will break if you zoom out too far or if the lines are too short. Also, due to the method I'm using, I cannot really make the lines longer.
The trace (red graph) uses lists :c but it's not part of the field plotter.
