Add clearer handling for chartex types whose rendering is not currently
supported. Previously, unsupported types defaulted to being rendered as
line charts, which could lead to confusion. With this commit, we instead
display a message stating that the chart type is not supported, and do
not attempt to render it.
Note that at this time, the message is hard-coded only in English
language text. In the short term it should be internationalised, though
in the longer term, the intent is that all chart types will be properly
rendered.
