Visualization beyond Excel

What’s wrong with Excel?

Both Excel and Tableau are great for exploration and presentation of data.

Its very recognizable.

Its both the tool and the viewer.

But, its not uncommon to see it in greyscale:

So, how can we make this a little more enticing?

Infographics

Infographics are intended to communicate a cohesive narrative that may include tables, graphs, diagrams, maps, etc.

They can be quite artistic to gain your attention.

How might graphic design principles help?

Limited attention: you have seconds to get and keep someone’s attention.

Limited memory: working and long-term memory

Limited perceptual channels: small number of things

Some of the elements of graphic design


Hierarchy

Scale

Color

Line

Shape

Alignment

Space

Contrast

Hierarchy

Read this second.

Read this third.

Scale

Scale affects how big or small your visualization can still be legible.

Or…

You may need to move things around a bit.

Color

Color swatches taken from a public domain image.

Here are some resources:

Line

Line weight helps to separate and define.

How does this look big? Or small?

Is it near or far?

So, you might adjust depending on your needs:

Shape

What do these shapes mean?

How might they be interpreted in the context of the narrative?

See Ferdio’s 100 visualizations with just 6 data points. https://100.datavizproject.com/#

Alignment

Alignment helps your reader orient themselves and predict where information will be.

The grid has a dedicated following.

Just a grid.

Space

This is the resting space around text and visuals. It gives the eye time to rest and move between salient points.

Also called negative space, or ground.

Contrast

This affects:
