+
+A Squiggle editor is simply a squiggle chart with a text editor rendered before
+it that allows the user to change the expression that is getting rendered.
+
+## Usage
+
+An example of a normal distribution is:
+<Canvas>
+  <Story
+    name="Default"
+    args={{
+      initialSquiggleString: "normal(5,2)"
+    }}> 
+    {Template.bind({})}
