All the dots are strange. Looks like they are not in the right places. You can check screen recording for better understanding.

import plotly.graph_objects as go

If you will try to build same set of dots in matplotlib, you will obtain more realistic results:

import matplotlib.pyplot as put

fig = plt.figure()
ax = fig.add_subplot(projection='3d')
ax.scatter(x, y, z)

plt.show()

Thanks @vertrue - this is a duplicate of plotly/plotly.js#5346 - low-precision of WebGL plots.
