+# Circles examples
+
+Run with `cargo run --release --package circles_example`.
+
+This example illustrates the following:
+
+1. Display a tooltip message in a Canvas.
+2. Make a Canvas change based on pushing a Button.
+3. Show that a Canvas is stil performant even when it has a large number of objects in it.
+
+Tested on a Mac.
