WS2812B led strips, Series or parallel?

[Daybear]

I have tried to find info on connecting WS2812B led strips Dat/signal line without any luck. I wondered if it was ok to connect the dat/signal line in parallel to 2 existing led strips from the controller or does it have to be in series?

The datasheet shows how to cascade:

See page 4.

Thank you for the info. Do I read it correctly that I have to connect the LED strips in series and that it is not possible in parallel?

The data is in series.
The power supply voltages are in parallel.
See last page example.
