'createObjectURL' error in IE9

I’m testing my dashboards in IE’s dreaded compatibility mode. They render correctly in IE11 and require polyfills in IE10 (but ultimately render correctly), but I’m running into an error in IE9:

SCRIPT5007: Unable to get property 'createObjectURL' of undefined or null reference
plotly-latest.min.js (7,809876)

error

This results in Plotly being undefined. Is there a workaround or fix for this?

The main plotly.js (as served on https://cdn.plot.ly/plotly-latest.js) does not support IE9. The exception you’re pointing to is due to our mapbox-gl dependency.

If you’re looking for IE9 support, please use of our partial bundles that only bundle SVG traces:

or bundle your own, more info:
