.visualize_hierarchy() not showing different cluster colors

[ttu-hq]

Hi Maarten,

I've been using BERTopic for a while and it's an amazing resource! Thank you for all your hard work. I'm wondering if you can help me with an apparent issue I'm seeing:

After updating to the latest version of BERTopic, I'm finding that the .visualize_hierarchy() function is not showing different cluster colors as it used to. I've checked my plotly installation and it's a supported version. Color_threshold is set to default. Not sure what I'm doing wrong. I've attached the PNG of the plot. Any suggestions/advice are greatly appreciated!

It might be worthwhile to play around with the different values for color_threshold. As a default, it is set to 1, so perhaps setting it to 0.5 or 2 changes the results.
