How to display items that make up a slice of a pie chart in Kibana?

I am attempting to create a pie chart that will display the health status of various systems. This is what the chart currently looks like:
Each data point, in addition to the possible errors messages, has a name in its data.
Is it possible to configure the chart so the system names are shown in the pie chart? In the tooltip for each slice would be preferable, but any solution will work.
You can Add (button at the buttom of the configuration) a second visualization, which will then add another layer around your first visualization.

You could use a smaller font:
PiePlot plot = (PiePlot) chart.getPlot();
int fontSize = 10; // Adjust the size here
plot.setLabelFont(new Font("SansSerif", Font.PLAIN, fontSize));
i was able to reduce this problem by showing the pie chart as a 2d pie chart rather than a 3d one. it gave me a final result like the one similar to the https://stackoverflow.com/a/13309587/230513 suggested by #trashgod
i think i will be able add more color to the solution by implementing the suggestion done by #obourgain
Thanks guys!
