[charts] Add an option to put bar label on top of the bar

[tejase]

Summary

inclusion of an option to display numerical values directly over the bars in bar charts. Currently, bar charts are effective in visualizing comparisons between different categories or groups. However, users often require precise numerical information corresponding to each bar to accurately interpret the data. By incorporating value labels directly onto the bars, users can effortlessly determine the exact values represented by each bar without having to rely on a separate axis or additional interaction.

Motivation

By incorporating value labels directly onto the bars, users can easily and accurately determine the numerical values associated with each bar without the need for additional cognitive effort or referencing separate axes or tooltips. This feature aims to streamline the data interpretation process, improve user convenience, and empower users to derive meaningful insights from their data with greater ease and precision.

Ultimately, the goal is to enhance the overall user experience of data visualization tools, making them more intuitive, informative, and conducive to data-driven decision-making processes.

@tejase I modified a bit the title because it overlaps with #12331

You can already see how it will be possible to add label on bar charts with PR #12988 Feel free to provide insight in the PR itself if you see missing aspect in the PR docs preview

@alexfauquette any update on adding labels on top of bar charts? Something like this?

Hi,

I just want to emphasise the importance of this feature when you are having stacked bars, as you then are lacking the possibility to easily see the total sum of each bar in the stack.

Even the tooltip should display a sum the values in the stacked bar.
