3D CAN BE CHARTJUNK
•Power View does not contain 3D functionality – why?
![Page 10: Power View from the Data Visualisation Perspective](https://reader035.fdocuments.net/reader035/viewer/2022062616/54b3b5684a7959a8438b4579/html5/thumbnails/10.jpg)
3D OR NOT TO 3D
•Power View does not contain 3D functionality – why?•People can overestimate the vertical dimension (Wansink, 2003)•3D space makes it too difficult to compare•Values•Volumes•Areas
•Distorts

TRELLIS CHARTS
![Page 12: Power View from the Data Visualisation Perspective](https://reader035.fdocuments.net/reader035/viewer/2022062616/54b3b5684a7959a8438b4579/html5/thumbnails/12.jpg)
PIE CHARTS
•Power View does not contain pie charts, at the time of writing… why?•We find it difficult to read angles•We find it difficult to judge areas•We can’t easily read over 5 slices very well•Each part must be mutually exclusive
![Page 13: Power View from the Data Visualisation Perspective](https://reader035.fdocuments.net/reader035/viewer/2022062616/54b3b5684a7959a8438b4579/html5/thumbnails/13.jpg)
PIE CHART EXAMPLE

PIE CHART EXAMPLE

PIE CHARTS – NOT ALL BAD!
•You can compare combinations of adjacent wedges•The parts should make a sensible whole•You’re just expecting the image to answer one ‘business question’ only•You do not need trendlines
![Page 16: Power View from the Data Visualisation Perspective](https://reader035.fdocuments.net/reader035/viewer/2022062616/54b3b5684a7959a8438b4579/html5/thumbnails/16.jpg)

MOTION CHARTS
•This makes even more of the limited space•We can pack more information in•Data / Ink Ratio•Motion is a pre-attentive attribute•Dependent on other items e.g. chartjunk
