Review Comment:
The head and shaft are not at the same level, in order to get their common
ancestor with the d3 selection API, we need to hard code like
```javascript
d3.select(d3.select(arrowHead.node().parentNode).node().parentNode).select("path")
```
It appears not future-proofing. The suitable way is using edge ID, but it
seems not supported by both graphdot-lib and dagre-d3 yet. In this scenario,
jQuery appears to be a suitable option based on our typical usage in UI.
