I like this pattern! But two comments about it:

  • trace.box and trace.meanline are deleted rather than left with visible: false - so can't we just say (trace.type === 'violin' && trace.box) etc?
  • I'm a bit uneasy relying on uninitialized vars being undefined - seems like it makes things more fragile, for example if we use fn again, or wrap this block in a loop or something... I'd rather a pattern like
var fn;
if(...) fn = Lib.identity;
else fn = []; // or just var fn = []; and drop the else, dunno which is better

var paths = sel.selectAll('path.box').data(fn);
