Try out the sample portal below, visualizing over 100,000 earthquakes worldwide.

Visit http://filtergraph.vanderbilt.edu on your desktop or tablet to see it in action.

This portal is interactive! As you change the settings on the left side, it will affect the graph on the right side. In addition, you can click and drag to zoom it, or retrieve information about a point with a single click. More examples: Kepler space telescope data, Hipparcos catalog

Filtergraph has been used to unlock the secrets of the universe.

A Vanderbilt graduate student has used Filtergraph on data from the Kepler space telescope to discover a relationship between the amount of flickering of a star and the gravity on its surface, a key discovery in our understanding of planets outside of our solar system.

What discoveries are waiting to be made in your datasets?
