5 1. Background to Data Viz

6 What is Data Visualization? Graphical representation of quantitative and qualitative data, such as chart, map, diagram, etc

7 The value of Data Viz in M&E Beautify Information Digest Detail Simplify Complexity

8 Origins of Data Viz Visual perception Source: Few, S. 2nd Ed. Data Visualization for Human Perception. (in) The Encyclopedia of Human-Computer Interaction, 2nd Ed. by Mads Soegaard, Rikke Friis Dam

11 Data Visualization Discipline Google Trends Interest over time Numbers represent search interest relative to the highest point on the chart for the given region and time. A value of 100 is the peak popularity for the term. A value of 50 means that the term is half as popular. Likewise a score of 0 means the term was less than 1% as popular as the peak.

14 Quantitative Qualitative Telling a story

15 Quantitative Data Viz Simple Graphical Solutions Chart Tactics Maps Static Dashboards Advanced Analytics Dynamic Dashboards Social Network Analysis R based tools

16 Chart Tactics The process of creating well researched and aesthetically pleasing infographics, charts, diagrams, and/ or maps to summaries data in a way that is quick and easy for the reader or audience to understand

17 Chart Tactics Based on comprehensive, and quality assured data Correct or appropriate to convey their message accurately and effectively. I.e. ensure that the chart, graph, map or diagram chosen is appropriate Ask: "What is your point?" - Stephanie Evergreen Clear and high quality with minimal clutter and with appropriate use of colour Similar throughout the document to create a strong visual theme throughout, using text size, font, style, icons and colour

25 Trend in scale Sorted Bar chart

26 Maps Describing location and scale in words can be challenging. Even graphs alone do not provide a clear spatial picture, i.e. how far one location is from another or how big it is compared to another. Maps allow us to condense and present spacial variation.

27 South Africa, Zimbabwe, Zambia, Malawi, Uganda, Somalia, Chad, Togo and Tunisia have the highest levels of indicator X Heat Map

28 Chart Overlays

29 Static Dashboards display a dense array of information in small amount of space and in a manner that communicates clearly and immediately. Few, S Information Dashboard Design. Analytics Press. Burlingame Types: Operational dashboards tell you what is happening now Strategic dashboards track key performance indicators Analytical dashboards process data to identify trends

36 Qualitative Data Viz Icons Timelines Photographic overlay

37 Icons Based on the themes and key points identified use symbols to emphasize enclosure and similarity. This reduces reading time as icon represents a statement or category.

38 "The key factors inhibiting schools from acquiring computers are: absence of electricity, lack of funding, insufficient building, lack of available and trained staff, poor security"

39 Timelines In long term projects the series of key events or even the complex stages of an evaluation can be hard to condense. Timelines allow us to tell the story of the sequence and complexity of events.

42 Photographic overlay Using photographs allows the reader a more detailed understanding of a context or perspective. It also arouses emotions and engagement. This is particularly useful when a writing style is not emotive, but there is a need to convey severity, or contextual detail.
