ThingSpeak offers a very easy way to create visualizations and even integrate them into your own homepage. This is done using widgets that are called with a line of code.
This article describes what standard display types are available in ThingSpeak and how easy it is to create these widgets.
A second article provides some examples of individual plots.
Finally, you can read in a third article how easy it is to integrate individual display elements into your Jimdo homepage.
On my honey page you can find some examples how this can look like.
I would be happy if further interesting analyses could be shared by others here.
