Sunburst Diagram- issues with customisation

Hello,

I am working with the dataframe outlined in code at the base and I want to create a sunburst diagram.

One of the main issues I am facing, is when i read the document, the composition of the diagam does not change. Firstly, when I am trying to change the font colour, with the code below, it only changes the parent in the centre. I also want to change the font type, but it seems the fonts all around are driven dynamically.

ideally I am just wanting some help on control- I would like the following:

  • To remove text within the graph and have it as a key legend only
  • To be able to make all fonts the same colour
  • To be able to edit the labels, so I can choose the information

fig.update_layout(
font_family=“Helvetica”,
font_color=“blue”,
font_size= 16,
#title_font_family=“Times New Roman”,
#title_font_color=“red”,
#legend_title_font_color=“green”

import pandas as pd

df = pd.DataFrame({
    'ELEMENT TYPE': ['ALUMINIUM WINDOW', 'GLAZING', 'CLADDING', 'CLADDING', 'UHPC', 'UHPC', 'UHPC', 'INSULATION', 'INSULATION', 'INTERNAL DRYLINING', 'DRYLINING SECONDARY SUPPORT', 'SHEET FIRE STOP', 'ALUMINIUM WINDOW MIDDLE TRANSOM'],

    })
fig = px.sunburst(Final_df, path=["Parent", "MATERIAL TYPE", "ELEMENT TYPE", "MATERIAL"], values = "MATERIAL IMPACT",
    width = 1500, height =1000,

    hover_data=["MATERIAL IMPACT"],

fig.show()

To customize any px plot, in particular px.sunburst, you should print
fig data and fig.layout, where, in this case, fig=px.sunburst. Then call help(go.Sunburst) to realize what px.sunburst has already set from the go.Sunburst attributes or layout, and perform updates according to your desired features.
