i1 : Polyline{PointList=>{[0,0],[50,50],[0,100],[50,150]},"stroke"=>"yellow","stroke-width"=>5,"marker-end"=>arrow(10,"fill"=>"orange"),Margin=>0.3}
o1 = Polyline{cache => CacheTable{} }
Margin => .3
PointList => {| 0 |, | 50 |, | 0 |, | 50 |}
| 0 | | 50 | | 100 | | 150 |
| 0 | | 0 | | 0 | | 0 |
| 1 | | 1 | | 1 | | 1 |
style => MutableHashTable{...3...}

The object arrow is a function closure.
