Hi, I’m using Plotly to display a dataset with a lot of points,[](https://geometrrydashapk.com/)and the chart becomes noticeably slow when zooming or panning. Is there a recommended way to improve the performance, without reducing too much of the data?

@lilyhazel265 have you checked this section of the documentation? [High performance visualization in Python](https://plotly.com/python/performance/) , it could give you a good idea of how plot rendering works. Also, you can figure out what figure type is best for you.
