Adding native support for histogram chart and its variations

This proposal aims to address the lack of support for histogram charts and other advanced chart types introduced in Microsoft Office 2016 within LibreOffice. Histograms are essential for data analysis, scientific research, and machine learning, providing valuable insights into data distribution. Currently, LibreOffice users rely on some clunky workarounds to create histograms, limiting productivity and compatibility with industry standards. The goal is to implement native histogram chart support in LibreOffice, eliminating the need for workarounds and enhancing the user experience. By leveraging the existing column chart implementation as a starting point, the project will gradually transform and extend the code-base to support histogram-specific functionality. This approach minimizes disruption to the stable code-base while introducing new capabilities.
