In some respects Blood Donation follows a lot of the traditional methods associated with Charity activity (positive success stories, the emphasis on the difference you can make etc.,) but where for most charities the aim is getting someone to make a donation (or even better set up a direct debit), for blood donation the barrier is even higher as it involves the potential donor's time and effort as well as a certain amount of physical discomfort.
The upside is where with some charities you may (probably falsely) wonder what difference your donation will make, by giving blood you can be sure that it really is something that is necessary to save lives.
This blog compares how the 3 organisations in mainland UK display details of their current stock levels, and where what should be a fairly straightforward visualisation seems to get a bit of a mangling.
The body for England & North Wales blood.co.uk shows 3 static charts when visiting its Stock Levels page:
|Current Days Stock: Fairly straightforward chart but again not sure about need for decimal point or 3D effect
The Scottish Blood Service go for a more infographic type approach:
Blood.co.uk where it isn't obvious it is now only dealing with part of the UK e.g., you enter Newport (Gwent) on the site and currently get told that nearest location is in Somerset.
Overall, for me the image from the Welsh Blood Service is by far the best representation of the data, it gives the information clearly in a format that can be understood easily and colour coded to flag up particular Blood Groups with immediate problems.
