remember the needs of your audience
the simplest way to ensure a visualisation is appropriate for a particular audience is to test it

DATA VISUALISATION SPECIFICATION1. Aims
4. Finishing
2. Data
3. Form
AudienceWho will be viewing your graphic?Consider: Age, gender, profession,education, nationality, language,existing level of knowledge about the subject.
MessageWhat is the key “story” told by your visualisation. Why is it important? Are you sure it can’t be communicated better verbally?
TimingPublication date.Does your visualisation havea shelf life, or need updating?
Comparting quantitative magnitude: Size (bar charts), area (pie / bubble charts), symbols (Isotype diagram).
Showing trends over time:Position (line graphs), animation Spatial data:
maps (but also consider if category is more importantthan physical location).
Showing categories and heirarchy:Colour, linking, enclosing
ToneFormal Instructive
Data typesIs your data numerical?Heirarcical? Qualitative?Locational?
What data is available?Does it need to be cleaned?
Does more need to be collected?
Do you need to present everythingfor your key message to be understood?
Confidence / UncertaintiesHow certain is the data? What is on the horizon / could happen?
What do you want your audience to do?Do you need to show them where to findmore information?
Make sure you have provided a key.

The Environment Agency, evidence and infographics…
Name Liane Bradbrook, Job Title Evidence Advisor Date May 2014 ! email [email protected]
We are the Environment Agency We are an Executive Non-departmental Public Body responsible to the Secretary of State for Environment, Food and Rural Affairs. We protect and improve the environment and make it a better place for people and wildlife. We operate at the place where environmental change has its greatest impact on people’s lives. We reduce the risks to people and properties from flooding; make sure there is enough water for people and wildlife; protect and improve air, land and water quality and apply the environmental standards within which industry can operate. Acting to reduce climate change and helping people and wildlife adapt to its consequences are at the heart of all that we do. We cannot do this alone. We work closely with a wide range of partners including government, business, local authorities, other agencies, civil society groups and the communities we serve.
The Environment Agency
Our fundingGovernment provides 62 per cent of our funding. The remainder comes from charging schemes such as environmental permits, rod licences and boat fee’s. We spend around 55 per cent of our income on flood and coastal risk management 28 per cent on environmental protection 12 per cent on safeguarding water resources and 5 percent on fisheries, conservation and navigation.
What does Evidence do?Research
Communities and Flooding Climate Change and Resource Efficiency Air, Land and Water Chemical Assessment Unit (UK environmental hazard & risk assessment expertise on behalf of Defra)

Our approach to visualisationComplex datasets &/or Visualisation for analysis
Narrative lead infographic products for engagement, more complex information. Some commissioned.
Developing in-house skills and capabilty, tackling non standard and custom graphics. Supporting incident response
Beyond excel standard outputs, Improving basic skills, making use of what we have: Powerpoint

Act to reduce climate change
and its consequences
We help England and Wales meet greenhouse gas
emissions targets in ways that minimise other
environmental impacts
We help people and wildlife adapt to climate change and reduce its adverse impacts
We put reducing and adapting to climate change
at the heart of everything we do
EA’s role in mitigation
Regulator of greenhouse gas emissions Regulator of low carbon technologies Deployment of low carbon infrastructure
Mitigation – reducing our greenhouse gas emissions through energy efficiency, reduced energy demand and renewable energy.
EA’s role in adaptation
Adaptation action plans exist for all our functions We embed adaptation in Agency roles and functions in particular flood risk, water resources and biodiversity Help others to adapt through the Climate Ready support service
Adaptation - preparing for the unavoidable impacts of climate change
The challenges1. Catchment visualisation tool2. Displaying sea level rise projections3. Displaying future flows information4. Displaying climate projections for a particular geographical location5. Communicating risk6. What does an adapted business look like?7. Business & Supply Chains8. Habitat impacted by coastal squeeze and habitat creation targets?9. Extreme weather events timeline10. Financial impacts of climate/weather on the economy11. Food security12. How local authorities can adapt to changes in climate
