Concatenation of variables in timelion scripts

[adityarar]

Enhancement Request

Describe the feature: Timelion provides provision for creating variable values to be referred later. Like $value=500. We can also use this while calling .label(...). It does not work if we do something like: .label('value used '+$value). Added a screenshot showing this.

It is useful in certain scenarios to have a string literal appended with the defined variable.

+1 would greatly improve maintenability on complex visualization were the current solution is to hardcode everything single string as soon as one char changes.
