title: How to apply horizontal break to a d3.js bar chart
body: <p>I am using Rickshaw (based on d3.js) to plot stacked bar charts. The problem is that the first bar is usually way more higher than the others, ruining the visual feedback.

  <p>Using logarithmic scale is (I guess) not an option here, because then the proportions between stacks in a bar will get broken. I wanted to introduce a horizontal break like in following image:

  <p>However, I cannot find any out-of-the box feature of Rickshaw or d3.js to do something like this. Any suggestions on how to make one?</p>
