Tiny plot output from sankeyNetwork (NetworkD3) in Firefox

Question

As per object, I get a very small plot in Firefox when using sankeyNetwork() from networkd3 in shiny but not in Chrome or RStudio.

I have not included any CSS or JS in the script - the code below produces this result for me.

Is there any CSS property I have missed?

I am using R 3.4.1, shiny 1.1.0, networkD3 0.4 and Firefox 52.9.0.

Firefox:

Chrome:

------------------ EDIT --------------------

Thanks to @CJYetman for indicating onRender() as a possible solution - however this fails when there are two plots generated side by side as in the MRE below (note in addition to the second sankey plot I have also added javascript code to re-draw the figures when the window size changes as the plot does not appear to do it automatically).

$(document).on("shiny:connected", function(e) {
    dimension[0] = window.innerWidth;
    dimension[1] = window.innerHeight;
    Shiny.onInputChange("dimension", dimension);
});
$(window).resize(function(e) {
    dimension[0] = window.innerWidth;
    dimension[1] = window.innerHeight;
    Shiny.onInputChange("dimension", dimension);
});
                            ')
  ),

------------------ EDIT2 --------------------

Second problem above solved - either by referring to the second svg item on the page as per @CJYetman's comment below using document.getElementsByTagName("svg")[1].setAttribute("viewBox",""), or by going into the objects themselves selecting their first svg element with document.getElementById("sankeyHSM2").getElementsByTagName("svg")[0].setAttribute("viewBox","").

Answer 1

This seems to be the result of Firefox reacting to the viewbox svg property differently than other browsers. It might be worthwhile to submit this as an issue here https://github.com/christophergandrud/networkD3/issues

In the meantime, you could work around this by resetting the viewbox attribute using some JavaScript and htmlwidgets::onRender(). Here's an example using a minimized version of your example. (Resetting the viewbox attribute may have other consequences)

library(htmlwidgets)
library(networkD3)
library(magrittr)

nodes = data.frame("name" = factor(as.character(1:9)),
                   "group" = as.character(c(1,2,2,3,3,4,4,4,4)))

links = as.data.frame(matrix(byrow = T, ncol = 3, c(
  0, 1, 1400,
  0, 2, 18600,
  1, 3, 400,
  1, 4, 1000,
  3, 5, 100,
  3, 6, 40,
  3, 7, 20,
  3, 8, 4
)))
names(links) = c("source","target","value")

sn <- sankeyNetwork(Links = links, Nodes = nodes, Source = "source", 
                    Target = "target", Value = "value", NodeID = "name", 
                    NodeGroup = "group", fontSize = 12, sinksRight = FALSE)

htmlwidgets::onRender(sn, 'document.getElementsByTagName("svg")[0].setAttribute("viewBox", "")')

---

UPDATE (2019.10.26)

This is probably a safer implementation of removing the viewBox...

htmlwidgets::onRender(sn, 'function(el) { el.getElementsByTagName("svg")[0].removeAttribute("viewBox") }')

---

UPDATE 2020.04.02

My currently preferred method to do this is to use htmlwidgets::onRender to target specifically the SVG contained by the passed htmlwidget, like this...

onRender(sn, 'function(el) { el.querySelector("svg").removeAttribute("viewBox") }')

That can then be done specifically to as many htmlwidgets on your page as necessary, for instance...

onRender(sn, 'function(el) { el.querySelector("svg").removeAttribute("viewBox") }')

onRender(sn2, 'function(el) { el.querySelector("svg").removeAttribute("viewBox") }')
