Height issue when all values are zero

[pptyasar]

When dynamic height is set and all values are zero than funnel is collapsed.

@pptyasar That issue is not nearly as pronounced in the latest version of the library. It appears your example is using v0.7.5 whereas the latest is v1.1.1. See the fork I created of that which shows that a funnel is rendered, although it does not fully respect the height:

I will be adding a fix that makes the funnel take up the remaining space in the instance that all values are zero.

This should now be fixed. See https://jsfiddle.net/s4qjuxry/4/.
