I just updated some code to work with v1.0 of Julia and Gadfly, and the SVG output from Gadfly that used to work fine with MS Office now renders without color, the svg editor Inkscape also renders it with no color.
using Gadfly, RDatasets
iris = dataset("datasets", "iris")
p = plot(iris, x=:SepalLength, y=:SepalWidth, color=:Species, Geom.point);
p |> SVG("test.svg",15cm,10cm)
While the resulting svg file looks like expected in a web browser, when inserted into MS Word it looks more or less like this: (png below exported to png from inkscape)
