On 24th August 2015 contains 725 policies. Interesting data, wanted to show in interesting ways! 18/09/2018 An Introduction to Data Visualisation

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 18/09/2018 An Introduction to Data Visualisation

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? 18/09/2018 An Introduction to Data Visualisation

ROARMAP data - http://roarmap.eprints.org/
Data Sets Used ROARMAP data - Open Access (OA) policy effectiveness study – collected by PASTEUR4OA Project Bibliographic metadata indexed by the Thompson-Reuters database (WoK) - Publication date was estimated based on the Altmetrics database and WoK publication date - 18/09/2018 An Introduction to Data Visualisation
13
Data Sets: Things to think about
Is it a reputable source? Is it openly available? How up to date is the data? Is the data easy to get out and work on? Has the data been manipulated? Are there omissions of data? Will you need to combine data sets? Do you need to add in other data e.g. country codes/names 18/09/2018 An Introduction to Data Visualisation

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. 18/09/2018 An Introduction to Data Visualisation
17
Data: Things to Think About
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 18/09/2018 An Introduction to Data Visualisation

27
HAVING SEVERAL MACHINES TO USE CAN BE USEFUL

Tools: Things to Think About
Does it cost to use? What is the licence? Do you have the correct OS? Can you get the visualisation out of the tool? Can you link to live data? Can you embed it? Can you make a graphic of it? Can you download it? Does the tool expect you to be able to programme? 18/09/2018 An Introduction to Data Visualisation

DELIVERING DATA VISUALISATIONS
31
Delivery: Things to Think About
Does it cost to use? What are the infographics going to be used for? What format should they be in? Is there a colour theme? What colours look good? Can you create a custom palette Can you distinguish between different parts of the chart? Is it clear what question the visualisation is answering? Is there enough information on the data visualisation? Is there a heading, comment box, labels, annotation, legend etc.? Is the result honest? Make sure you document where all the visualisations are 18/09/2018 An Introduction to Data Visualisation
