Bus 101: Lecture 6 Flashcards
Steps to creating a good visualization
understand the context, choose the right visual, remove clutter, focus the audience’s attention.
Which visual is the best for displaying changes, patterns, and relationships?
charts and graphs
If you just need to communicate one number…
just use that number.
heatmaps
leverage colour to focus attention to specific points.
column and bar charts
used for categorical or discrete data
for bar charts…
the axis should always start at zero.
waterfall charts
best used to show a starting value, and then changes that result in a final value.
line graphs
used for continuous data
scatter plots
show the relationship between two data points

pie charts
commonly used; not effective as it is hard to judge area.
3D charts
only add clutter to the data set.
colour blindness
the most common form is red-green colourblindness.
