hey, @bpostlethwaite the batch app is using only basic plot types: https://github.com/plotly/plotly.js-batch-reporter/blob/master/src/App.js#L9

is this what we want? should we try with the full plotly.js library of traces?

this also makes me think that we don't have icons for absolutely ALL plotly.js chart types, I guess we can just use a stub icon in the meanwhile, for the plot types we don't have an icon for

For now it is - see https://github.com/plotly/plotly.js-batch-reporter/blob/master/src/components/CustomPanels.js#L49-L61
