[okfn-labs] Ideas for data mashups and improved visualisation for CKAN

Wed Jul 24 16:47:05 UTC 2013

Hi everyone,

Just to give you a different point of view, due to the usage that I'm doing
of CKAN :-)

Several of you have said that people might not find it interesting to embed
data viz on websites, because the data comes from governments. However, in
my case, specially in the case of PyBossa, the data may come from
scientific projects, and I guess people will actually like the option to
embed the viz in a simple way ;-)

I completely agree with Friedrich about the complexity of drawing
everything for every data type is very complex, so probably, exporting the
data using third-party tools in a simple way would help as suggested by
Gavin.

In any case, from the PyBossa point of view, it would be very helpful to
have what Friedrich has suggested as well as a simple tool for creating
some charts.

All the best,

Daniel
