What is Data Storytelling?

Data storytelling is not data visualization

Data storytelling connects your narrative with data visualization

Data Storytelling makes data meaningful for the audience

It works on the why aspect of data - why is the data relevant to your audience? What should they do with it?

Current context of data revolution. There is too much information. If you want to make an impact, you have to contextualize your data.

Simple Text

Tables?

Heat Map: Colour Intensity

Scatter Plot: Relations

Slope: Change between two points

 

BAR GRAPHS

Visualise

Effort in processing?

 

Attention is divided?

Visualise

Heatmapping - Great for picking up big differences, not so great for minor ones

 

Bar Graph: See the change

 

Line Graph: Best for end point comparisons

 

 

 

Visualise

Avoid clutter to reduce cognitive load

 

Leverage white space and align elements

Gestalt Principles
