Data Visualization Tools- Questions and
Answers |Latest Update
By most positive or most negative (the number of positive outcomes will go to the right and the
number of negative outcomes will go to the left) How are diverging bar charts generally
sorted?
Not as quick and easy to understand as vertical bar charts What are the cons of diverging
bar charts?
Treemap - Display hierarchical data as a set of nested rectangles. Each branch of the tree
is given a rectangle, which is then tiled with smaller rectangles representing sub-branches.
- Alternative way of visualizing the hierarchical structure of a tree diagram while also displaying
quantities for each category via area size.
- How the whole is divided: for each level of the hierarchy, it is easy to understand which entity
is the most important and how the whole is distributed among entities.
- How the hierarchy is organized. What are the two types of ways treemaps are used to
show information simultaneously?
Speedometer (Gauge Charts and Dial Charts) - Shows the maximum, the minimum, and
the present value of data being analyzed.
Scatterplot - A data visualization tool that displays a set of points plotted on the horizontal
and vertical axis used to observe and show the pattern or relationship between variables. -
, Relationships between the variables may be described as positive or negative, strong or weak,
linear or nonlinear.
When trying to determine whether two variables are related. When can a scatterplot be
used?
- Illustrates trends
- Can work well with large quantities of data What are the pros of scatterplots?
Correlation is sometimes confused with causation.(scatterplot may reveal correlation, but doesn't
provide info on causation) What are the cons of scatterplots?
Waterfall - Expresses a visual example of how cumulative effects work on data. This chart
can be used to show how the starting value is influenced by a series of values.
-- Also known as flying bricks chart, Mario chart, or bridge due to its distinct look.
- Inventory or performance Analytics
- Common in financial values
- Can display quantitative data What are the uses of waterfall charts?
- Distinct suspended block view
- Color coordinated
