4. WRITING A SPECIFICATION

5. Data Viz Brief
Exploit the ROARMAP database and create visuals to be produced for advocates to use in presentations, literature etc.
Develop ways to show the statistics in an attractive form, e.g.:
Maps (Europe, the world, individual continents) showing where policies are
Charts showing data such as funder type, what is mandatory, etc.
Create interactive online visualisations using data dumps
Use live data if possible
For policy makers, institutions, researchers, individuals

6. Spec: Things to think about
What is the budget for the work?
How much time and resources are available for the work?
How will you get the data out of the system it is in? API, URL or other?
Where will you store the visualisations?
Where will you store the new data created? Will you release it openly?
How often will the data be updated?
Who can help you with your work?
What is genuinely do-able?

15. MANIPULATING DATA

16. Useful Excel Functions
Sum – adding up
Count – the number of cells in a range that have numbers in them
Vlookup - lets you search for specific information in your spreadsheet
Concatenate – lets you combine text from different cells into one cell
Trim – removes extra spaces
Substitute – like replace but more versatile
Sheet/page layout – hide rows, filter data, lock columns etc.

You do need to be able to use excel…well
Have you checked your data recently?
Have you saved versions of your data and labelled them well?
Are you keeping notes about what you are doing?
Are you being consistent with your data?
Make sure you document processes
Countries can be tricky – make sure you are clear and consistent
