<p class="Normal"><strong>Be sure to explore the many example programs that are installed with Visual. </strong><br />
</p>
<p class="Normal"> </p>
<p class="Normal">To invoke the Visual
module, place the following statement at the start of the file:</p>
<p class="program"> from visual import *</p>
<p class="Normal">To make sure that 3/4 is treated as 0.75 rather than zero, start your program with these statements (there are two underlines before <strong>future</strong> and two underlines after <strong>future</strong>):</p>
<p class="program">from __future__ import division<br />
from visual import *<br />
