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.

|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

Jerusha Govender | jerusha@thedatainnovator.com | @datainnovator

slide-17
SLIDE 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

|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.

|Static Dashboards

  • “display a dense array of information in small

amount of space and in a manner that communicates clearly and immediately.”

Few, S. 2013. 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

Jerusha Govender | jerusha@thedatainnovator.com | @datainnovator

slide-37
SLIDE 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.

"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"

Jerusha Govender | jerusha@thedatainnovator.com | @datainnovator

slide-39
SLIDE 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.

|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.
