Description

When opening Topology Visualization, below error is shown to the console of browser:

visualization.js:314 Uncaught TypeError: Cannot read property 'default' of undefined
    at gather_stream_count (visualization.js:314)
    at Object.<anonymous> (visualization.js:117)
    at Node.<anonymous> (arbor.js:35)
    at Function.each (jquery-1.11.1.min.js:2)
    at Object.eachNode (arbor.js:35)
    at Object.redraw (visualization.js:114)
    at screenUpdate (arbor.js:33)

This is due to the fact that some executors doesn't have stats for ':transferred'.
Below is the part of API response, and you can see some executors are having children for ':transferred' whereas others are not having children.
