Can you upload project and layer? Only a small subset of expression functions have been written, but if it's not a spatial function, it could be easy to add in.

Ah, there's a another more fundamental issue. I don't think expressions in the "graduate on" field are supported yet. nor is `toreal()` as far as I can remember, but the...

OK, the projections issue doesn't sound very easy to solve, unless we could simply use a single one regardless of webmap area. Yes, I've looked at d3maprenderer - see the...

@chriszrc Is performance better, worse, or comparable? Obviously, download is quicker, but I've never worked with topoJSON, so I don't know how well Leaflet and OL handle it.

Hrm. An initial search suggests that QGIS might not export to TopoJSON. d3 Map Renderer (QGIS plugin) uses Node, which is a non-starter here. How best to convert? Perhaps call...

Ah, OK, that should work (*waves @calvinmetcalf*). If there's no downside to this, and it can help with filesize, we can definitely look at this, but lets put it under...

@magayait You don't need to edit the code to add a scale line. Enable the scale line in QGIS (`View` > `Decorations` > `Scale Bar` > `Enable scale bar`) and...

I think it is recently possible in OL - will investigate.

Doesn't work brilliantly well: 

OL: I've not coded something for Leaflet yet - I'll need to identify a suitable plugin.
