How do I combine dcc.Interval, extendData, and px.scatter?

Hi, I’m attempting to minimize the wait time for a large animated px.scatter graph to render by displaying just the first few seconds initially and then load the rest of the data in the background and then add it to the graph (potentially while it’s already playing). It’s not clear from the documentation how to use the extendData with Plotly Express to do this (or if it’s even possible). Most examples are using go.scatter and adding frame by frame. I’m hoping to process larger chunks at a time and dynamically add them to an animated graph without noticeable delay/jitter. Is this possible and if so what is the exact technique used to do so? Thanks!
