Choropleth maps of London Boroughs

Please find below a choropleth map the population densities in the various London boroughs. Barking and Dagenham 12900 peop/sqm Barnet 10397 people/sqm Bexley 9752 peop/sqm Brent 15365 peop/sqm Bromley 5389 peop/sqm Camden 28024 peop/sqm City of London 6250 peop/sqm Croydon 10344 peop/sqm Ealing 14855 peop/sqm Enfield 9291 peop/sqm Greenwich 12500 peop/sqm Hackney 29783 peop/sqm Hammersmith and Fulham 26809 peop/sqm Haringey 19702 peop/sqm Harrow 11806 peop/sqm Havering 5446 peop/sqm Hillingdon 5957 peop/sqm Hounslow 10958 peop/sqm Islington 33815 peop/sqm Kensington and Chelsea 36218 peop/sqm Kingston Upon Thames 11752 peop/sqm Lambeth 27461 peop/sqm Lewisham 19639 peop/sqm Merton 14380 peop/sqm Newham 17175 peop/sqm Redbridge 12420 peop/sqm Richmond Upon Thames 8611 peop/sqm Southwark 25763 peop/sqm Sutton 11471 peop/sqm Tower Hamlets 31180 peop/sqm Waltham Forest 15150 peop/sqm Wandsworth 21890 peop/sqm Westminster 30531 peop/sqm After wasting too much time colouring in maps using MS Paint, I thought there must be an easier way, so I had a go at drawing a stylised map of London borough using SVG.

Most of free svg maps online used paths to trace each borough, I wanted polygons so I had to draw it from scratch.
The population densities are calculated from wikipedia figures from the 2011 census.

I've used html titles for the tooltips.

The map renders fine in Chrome 27.0.1453.116, not at all in internet explorer 9.0.8112, haven't tried it in Firefox.

I'm not sure about the colour scheme, greyscale looks okay for the time being. Any suggestions and critique would be gratefully received.
