i installed kibana-d3-sankey-master.zip from [https://github.com/ReneU/kibana-d3-sankey](https://github.com/ReneU/kibana-d3-sankey), via kirbana.plugin bat but when i tried to use the new vis icon for sankey, i got category not found error. i commented those and got beyond the error. when i try again, i get this error: [visualization] \> \_vis$API is undefined ---

Hi @Manny_Juan, I'd suggest opening an issue on that plugins Github page for assistance. Based on the one open issue there, it appears like the plugin is only designed to work with version `5.2.1`, but I haven't confirmed this. ---
