Loading custom JS chart into editor fails.

[deecay]

Issue Summary

Saved custom JS chart visualization does not load in editor.

Steps to Reproduce

1. Select Custom Plotly chart and select xAxis and a yAxis.
   I chose select ID, org_id from events LIMIT 10 from Redash metadata.

2. Paste the following to Custom Code.
   Line chart correctly renders.

Plotly.plot( element, [{
    x: x,
    y: ys }]);

3. Save

4. Click Edit.
   The error is raised and I see default template comments in Custom Code. Am I doing something wrong?
