UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.
Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/
sudo amazon-linux-extras install docker
sudo service docker start

I combined Mike Bostock's Zoomable Sunburst and Sunburst Partition examples, so that I could have both zooming and updating the underlying data (between count and size, in this case). A simple combination of the examples does not work; you have to edit the arcTween function used for updating the data, so that when it redraws the partition layout, it takes account of the current zoom level by adjusting the domain of the x scale.
Click on any arc to zoom in, and click on the center circle to zoom out. Use the Size/Count radio buttons to update the data.

| raised an exception. In addition, it also reports how long the task took |
