How to render text annotation on frontend? #1071

I am working on cell counting model and using DSA+Histomics for it, Can i also include a text number in the middle of the region of interest for which the nuclei segmentation boundaries are generated?

I was able to create annotation using numpy which "draws" those characters instead of being able to pass "text" type annotation.

annotations.append({
                'type': 'polyline',
                'points': [[segment[0][0], segment[0][1], 0.0], [segment[1][0], segment[1][1], 0.0]],
                'closed': False,
                'fillColor': 'rgba(0,0,0,0)',
                'lineColor': color,
                'lineWidth': line_width
            })

There is an intent (not realized) of having an option to render the labels on each annotation element. One of the reasons it hasn't been implemented yet is that we have to decide what to do when there are massive numbers of elements, as that will slow rendering down critically. Adding a text annotation would be another approach.
