Hey,

Does Plotly.js use asynchronous functions?

I haven’t been able to find anything in the docs

`Plotly.toImage` and `Plotly.downloadImage` are async except with option `{format: 'svg'}`.

`Plotly.newPlot`, `Plotly.restyle`, `Plotly.relayout` and `Plotly.react` are in general async, but more often than not aren’t. The only async behavior comes from fetching topojson/tiles data (for `geo` and `mapbox` traces) and rendering MathJax in text labels.
