9. Dimensions and Measures, Blue and Green
● Dimensions contain qualitative values (such as names, dates, or geographical data). You can use
dimensions to categorize, segment, and reveal the details in your data. Dimensions affect the level of
detail in the view.
● Measures contain numeric, quantitative values that you can measure. Measures can be aggregated.
When you drag a measure into the view, Tableau applies an aggregation to that measure (by
default).

11. Visual Design Basics
Visual design aims to improve a design’s/product’s aesthetic appeal and usability with suitable
images, typography, space, layout and color. Visual design is about more than aesthetics. Designers
place elements carefully to create interfaces that optimize user experience and drive conversion.
Actually, you use visual design to create and organize elements to
A) lead the user’s eye to an item’s functionality, and
B) make the aesthetics consistent.

12. Elements and Principles of visual design:
1. Lines (straight/curved/geometric/organic) – use these to create divisions, textures and
shapes.
2. Shapes – use lines, different colors, etc. to create enclosed/self-contained areas.
3. Negative space/whitespace – use the blank area around a “positive” shape to create a
figure/ground effect or calm the design overall.
4. Volume – use this to show the rich fullness of all three dimensions of elements on
two-dimensional screens.
5. Value – use this to set the relationship between lightness and darkness, typically through a
light source to create shadows and highlights.
6. Color – use this to set the theme/tone and attract attention.
7. Texture – use this to define an object’s surface.

14. Elements and Principles of visual design:
1. Unity – use this to establish harmony between page elements, so they
appear to belong together and users aren’t distracted by chaotic (e.g.,
misaligned) layouts.
2. Hierarchy – use placement, font, etc. to show importance.
3. Balance – use this to distribute elements evenly.
4. Contrast – use differences in color, etc. to accentuate elements.
5. Scale – use this to emphasize elements to establish importance or depth.
6. Dominance/Emphasis – use an object’s size, color, etc. to make it stand out.

23. Position, color, size,
shape, and orientation are
variables applied to
individual graphic elements.
Graphic elements are the
units of information that go
into making a figure, slide,
or poster. These include
photos, icons, paragraphs
of text, and titles.

24. Contrast: Elements have noticeably
different visual characteristics then
others in the composition. Created using
the variables of color, size, shape,
orientation.
Repetition: Elements have consistent
visual characteristics within the
composition. Created using color, size,
shape, and orientation.
Alignment: Elements have been arranged
to create an imaginary line within the
composition. Uses the variable of
position.
Proximity: Elements are close together
within the space of a composition. Uses
the variable of position.

25. Hierarchy: A dominant-subordinate
relationship among elements.
Grouping: A relationship that specifies
the elements to be associated together.
Sequence: A relationship among
elements that specifies first, second,
third…
