Hi Craig,

One   way is described here

http://docs.geoserver.org/stable/en/user/styling/sld-extensions/rendering-transform.html#heatmap-generation

So, what you could do is to expose the event layer as an SQL view to
Geoserver, and then use the newly added WMS layer functionality to serve
the layer from Geoserver to DHIS2.

Regards,
Jason
