 - The recommended `height` of the app is `50+(height of the plotly figure)`.
 - For the `port` of the app, make sure you don't pick the same `port` as another `molplotly` plot otherwise the tooltips will clash with each other. Also, apparently on windows port numbers below `8700` are used by other processes so for safety processes keep to numbers above that.

 JupyterDash is supposed to have support for Google Colab but at some point that seems to have broken.. Keep an eye on the raised issue [here](https://github.com/plotly/jupyter-dash/issues/10)!
 Update (1st March 2022): The plots seem to be running again but the hoverboxes are not showing so I don't think it has been fully fixed - I will keep an eye on it in the meantime.

 An issue/feature request for this has already been raised [here](https://github.com/wjm41/molplotly/issues/4).
 
 `moltplotly` works using a Dash app which is non-trivial to export because server side javascript is needed in addition to HTML/CSS styling ([as detailed here](https://stackoverflow.com/questions/60097577/how-to-export-a-plotly-dashboard-app-into-a-html-standalone-file-to-share-with-t))
 
 Until I find a way to get around that, the best alternative is to either host the plot on an app/server, exporting the plotly figure without molecules showing :( as detailed in this [page](https://plotly.com/python/interactive-html-export/). If you want to use it in a presentation I'd suggest keeping the figure open in a browser and changing windows to it during your talk!

+## Warning about memory size
 
 Just adding a warning here that memory usage in a notebook can increase significanly when using plotly (not `molplotly`'s fault!). If you notice your jupyter notebook slowing down, plotly itself is a likely culprit... In that case I'd consider either using plotly with [static image rendering](https://plotly.com/python/renderers/#static-image-renderers), or ... use [seaborn](https://seaborn.pydata.org/index.html) :P
