Feature

What is the expected behavior?

There are many charting applications that require annotations. This is not significantly different than a regular data series, except that it is usually sparse on the X-axis, and in addition to having a Y-value, it also has an associated text property. The codepen example below (from a different component) shows a version of how this might work. I could see config options for controlling whether the annotation text shows on hover or on click, "dot" symbol selection and customization, etc.

Maybe this component could be integrated to ReCharts? https://react-annotation.susielu.com/

PS - If anyone with solid React and ReCharts experience is interested in developing this feature, I'm willing to fund the project.
