feature request: Bubble chart

[Nexokk]

Hi,

First off, thanks for all your hard work on xlsxwriter. It's been super helpful for my projects!

I wanted to ask if you could add support for bubble charts. These are the charts where you can show data points with x, y coordinates and a size factor, all in one go. They're great for visualizing three dimensions of data in a clear and concise way.

Why Bubble Charts?

I'm working on a project where each data point is defined by three parameters. Bubble charts are perfect for this kind of data, but right now, xlsxwriter doesn't support them. It would be amazing if it did!

Benefits:

• Better Visualization: Bubble charts help to see three dimensions of data at once.
• More Insights: They can reveal patterns and correlations that other charts might miss.
• More Flexibility: It would make Rust xlsxwriter even more versatile for various data analysis tasks.

I really think adding bubble chart support would be a great addition to the library. Thanks for considering this request and for all the awesome work you do!

Cheers, Nexokk

I'll have a look at it to see what is involved.

Could you give a few real world examples of bubble charts you would like to create. In particular I am interested to know how/if you set the bubble sizes. Sample Excel workbook(s) would be best.
