Multi-line labels for long labels in chord diagram

[dstone42]

I am making this chord diagram in an R shiny app. The labels are very unruly and distract from the figure a lot. I attempted to fix this by making the labels multi-line. I added \n characters every 25 characters to the labels. This plot below is the result. I guess since this is being rendered in javascript, it ignores my \n characters and still just puts the label on one line.

I would love it if you would add this functionality to allow me to label this plot how I want. As I'm following a specific set of guidelines/naming conventions, I would like to avoid changing the actual text in my labels.

In case anyone else stumbles on this issue, I have a post-rendering patch that I'm using as a temporary fix. Although, I hope they fix this in the long run. It also requires you add some character into the labels that you can break on. I added '
', but you can technically add anything you want that isn't in your labels already. You would just have to change the patch to split on that.

        var text = d3.select(this).text();
        if (text.indexOf('<br>') !== -1) {
          var lines = text.split('<br>');
          d3.select(this).text(null);
          for (var i = 0; i < lines.length; i++) {
            d3.select(this)

          }
        }
      });
    }, 300); // Wait for rendering
  });
