 # mpld3Drag
 Testing custom plugins for mpld3. The plot is created with `matplotlib` and rendered in `d3.js` using `mpld3`. This is based on [http://mpld3.github.io/examples/heart_path.html] (http://mpld3.github.io/examples/heart_path.html).
 {% endfilter %} 13
17. @svenkreiss Feature: mpld3 fig = matplotlib.pyplot.figure(figsize=(8,4)) 
 // create figure here
 mpld3pi.signals.emit(‘mpld3canvas', mpld3.fig_to_dict(fig))
 
 <div id="mpld3canvas"></div>
 databench.genericElements.mpld3canvas($("#mpld3canvas")); 14
