Hi Frank,<div><br></div><div>I have been able to reproduce the DVI issue on a virtual machine running Kubuntu- all the text seems smashed to one point and the actual graph is shifted off of the page. This issue also shows up in MaxDvix but strangely the yap previewer on windows is rendering just fine. Hopefully there's a switch we can throw somewhere that will sort this out.</div>
<div><br></div><div>As for defining a macro to reduce the size of the text file- the problem is that the actual drawing of the circles is handled by the circle graphics primitive. At that level it's hard to tell that "this circle is one of 200 plotting points that are all exactly the same, use this shortcut" or "this circle is unique- we need to print out a fully styled command".</div>
<div><br></div><div>One option that I have been pondering is overhauling the styling system it's self. The styles are all the commands that appear between the [ ] in TikZ commands. Currently these make up ~80% of the command and there may be a way of caching and reusing them.</div>
<div><br></div><div>Anyway, thanks for the bug report- we'll let you know if we figure out a solution!</div><div><br></div><div>-Charlie</div>
