Does this library support dynamic rendering? I tried to add extra elements to the illustration after rendering it to the canvas and it doesn't appear to work. I might be using the API incorrectly though - is the idea that you can use this library to produce a static model which can then be transformed (eg. rotated), but can't be extended after the first render?

Did you try to call updateGraph() after adding elements? It seems like it should do the trick. [] https://zzz.dog/api#anchor-updategraph https://zzz.dog/api#anchor-updategraph

  This was my initial attempt using an Illustration https://codepen.io/anon/pen/NVORrZ https://codepen.io/anon/pen/NVORrZ This is my 2nd attempt using the docs you linked https://codepen.io/anon/pen/QRZKxy?editors=0010 https://codepen.io/anon/pen/QRZKxy?editors=0010 What do you think - is updateGraph + render supposed to work more than once?

    No, the underlying flatgraph (which is used to generate the drawing commands) is cached and only updated on first call. Reset it by calling scene.updateFlatGraph(); after adding new shapes, before updating the graph & rendering (see https://github.com/metafizzy/zdog/blob/master/js/anchor.js#L126 https://github.com/metafizzy/zdog/blob/master/js/anchor.js#L...) edit: made an issue https://github.com/metafizzy/zdog/issues/21 https://github.com/metafizzy/zdog/issues/21
