Lines vs lines+markers load time

Hello all,

I got a dilemma. I would like to use ‘lines+markers’ but the load time is horrendous compared to ‘lines’. It’s 10x slower. Is any way to optimize it? Thanks

CORRECTION: I found it’s very slow in FF (56.0.1 (32-bit)) but not Chrome.

We might want to look into scattergl:

I found an example using scattergl. Not sure if it even is ‘scattergl’. However, I copied and ran it but it’s about 5x slower than ‘scatter’. Do you know of any good examples? I only running pure html and javascript. No python. Thanks.
