Describe the bug I am getting Array buffer allocation failed error when I try to generate a 3D plot with a huge number of data points in it. Here is my code to reproduce the error when using n=2500

import dash
import dash_core_components as dcc
import dash_html_components as html
import numpy as np
import plotly.graph_objs as go

def get_figure(n):
    x = np.linspace(-100, 100, n)
    y = np.linspace(-100, 100, n)
    xx, yy = np.meshgrid(x, y)
    r = np.sqrt(xx**2 + yy**2)
    zz = np.sin(r) * np.cos(xx)
    return go.Figure(
        data = go.Surface(z=zz),
        layout=dict(width=600, height=600))

app = dash.Dash(__name__, suppress_callback_exceptions=True)

server = app.server
app.layout = html.Div(
    dcc.Graph(
        figure=get_figure(n=2500)
    )
)

if __name__ == '__main__':
    app.run_server(debug=True)

Expected behavior Here is how it looks when I lower the value n, to n=800. I expect dash to render the 3D plot without a problem at n>=2500 but it gives me the Array buffer allocation failed error.

Hi - we are trying to tidy up the stale issues and PRs in Plotly's public repositories so that we can focus on things that are still important to our community. Since this one has been sitting for several years, I'm going to close it; if it is still a concern, please add a comment letting us know what recent version of our software you've checked it with so that I can reopen it and add it to our backlog. Thanks for your help - @gvwilson
