Update/Refresh Data

[O]

I'm trying to create an update button for my bar chart.

Right now I'm testing to see if I can update the individual bars in the chrome dev tools or via something like this:

from: http://stackoverflow.com/questions/15352201/d3-update-dataset-on-click-and-redraw-the-bar-chart

Having a lot of trouble, any help would be appreciated. Here's my code:

I was able to get the update kinda working on this older version of the chart, any help?
