+"""
+This example demonstrates a very basic use of flowcharts: filter data,
+displaying both the input and output of the filter. The behavior of
+he filter can be reprogrammed by the user.
+
+Basic steps are:
+  - create a flowchart and two plots
+  - input noisy data to the flowchart
+  - flowchart connects data to the first plot, where it is displayed
+  - add a gaussian filter to lowpass the data, then display it in the second plot.
