+# Step 6. Build Network Topology and Graphical Display
 
 In this step we're going to get the network topology data and have a separate graphical tool Cisco [NeXt UI](https://developer.cisco.com/site/neXt/) parse the data and graphically render the topology.  We'll also use a web server tool called [Flask](http://flask.pocoo.org/) which well use to interface with NeXt UI.  Flask is a Python module

 ## Things to Try
 * Compare the first three layers of the topology to what you drew in step 5.  Do they match?
-* Go to the templates directory and open the file topology.html.  In the javascript block identified within block *<script type="text/javascript">* change the width and height from 800 to 400. Rerun the program. What's changed?
