## Instructions
<section id='instructions'>

<strong>Note</strong><br>Fun fact - D3 can plot 3D arrays.
The <code>positionData</code> array holds sub arrays of x, y, and z coordinates. Use a D3 method to find the maximum value of the z coordinate (the third value) from the arrays and save it in the <code>output</code> variable.
