visualizr - Show your data Once in a while I get in touch with lots of time based data, such as monitoring or profiling values.

Calls per minute, actions per time unit and so on. Having such data is a great value but having it visualized gives a different impression instead looking at numbers. I’ve created visualizr. It’s a small Single-Page-Application with a Java-based backend. Visualizr provides support for multiple data sources (a data source can contain multiple charts), auto-reloading and a great user experience.

Give it a try, you can find the code at or as a maven artifact (SNAPSHOT-version until now)
