Plotly.express not working with Pandas Dataframe #4179
Description
The example below results in an error message saying “AttributeError: 'DataFrame' object has no attribute 'append'. Did you mean: '_append'?”. The plotly example is taken from https://plotly.com/python/radar-chart/.
Running Plotly Version: 5.14.1 and Pandas Version: 2.0.1.
import plotly.express as px
import pandas as pd
df = pd.DataFrame(dict(
r=[1, 5, 2, 2, 3],
theta=['processing cost','mechanical properties','chemical stability',
'thermal stability', 'device integration']))
fig = px.line_polar(df, r='r', theta='theta', line_close=True)
fig.show()

Same here. Seems like the append function was depreciated, and it needs to be replaced by concat.
