plotly subplots: is it possible to have one subplots occupy multiple columns or rows

Question

I am trying to have 3 plots on one figure using plotly subplots. Naturally, I could do just 3 rows but I am trying to have first two figures side-by-side and another being stretched out. Overall I am trying to get a layout on the picture (that I made with paint): Is it possible and if yes how can I achieve this ?

Answer 1

From the documentation examples, using specs to define multi col span:

from plotly.subplots import make_subplots
import plotly.graph_objects as go

fig = make_subplots(
    rows=2, cols=2,
    specs=[[{}, {}],
           [{"colspan": 2}, None]],
    subplot_titles=("First Subplot","Second Subplot", "Third Subplot"))
