Line 1: Line 1:
List each item you identify using the following format.  The easiest way is to copy and paste the template.  For now don't bother grouping them, we'll collect a bunch first and then see what the appropriate categories are based on what we find.


Google Doc instead?  Yes
Pattern
# Another pithy idea.  Why it's important.  How to accomplish it. ['''Where It's From''', page number/URL. curator initials]
Example
# Choose color combinations with good contrast.  This makes it easier for people to separate the principle components.  Identify a set to use and then ask your colleagues for feedback, use a web-based color choosing tool.  ['''Charlie's Book of Viz''', page 33.  cfp]

Start-Up
* "Excellence in statistical graphics consists of complex ideas communicated with clarity, precision, and efficiency. Graphical displays should:
** show the data
** induce the viewer to think about the substance rather than about methodology, graphic design, the technology of graphic production, or something else
** avoid distorting what the data have to say
** present many numbers in a small space
** make large data sets coherent
** encourage the eye to compare different p[pieces of data
** reveal the data at several levels of detail, from a broad overview to the fine structure
** serve a reasonably clear purpose: description, exploration, tabulation, or decoration
** be closely integrated with the statistical and verbal descriptions of a data set"
** - "The Visual Display of Quantitative Information", pg. 13
* "Graphics should be reserved for the richer, more complex, more difficult statistical material." - "The Visual Display of Quantitative Information", pg. 30
** Integrate supportive text to the plotting filed to make the information perception easier for the viewer
** The size of type could be quite small
** Words on and around the graphics are highly effective in telling viewers how to allocate their attention to the various parts of data display
** For graphics words should tell the viewer how to read the design and not what to read in terms of content
** Make the reader choose how to perceive an information, do whatever it takes to understand the material (from presentation)
* Graphical practices
***Horizontally stretched time-series are more accessible to the eye (186)
***Shaded, calm, high contrast display might be better (187)
***Ease of labeling: easier to read from left to right on a horizontally stretched plotting-field (187)
***Emphasis on casual influence (187)
***Wider-than-tall shapes make it easier to follow from left to right (188)
***Include labels directly on the picture (43)
***Important comparisons among images should be pointed out to viewers by means of annotation, arrows, labels, highlighting (45)
***Useful to show both unmapped and mapped images (45)
***Every image should always reside on the universal measurement grid of 3-space and time, should accompany rescaling and zooming in and out (45)
*** Reports immense detail, organizing complexity through multiple and hierarchical layers of contextual reading (38)
***Words are spelled out, elaborate encoding is avoided
***Words run from left to right
***Little messages help explain data
***Elaborately encoded shadings, cross-hatching, colors are avoided. Instead labels are placed on the graphic, no legend required
***Colors if used are chosen so that color-deficient/ color-blind can make sense of it (choose blue)
***type is clear, precise, modest
***Type is upper and lower case, with serifs
***the more the letters are different from each other, the easier is the reading
***all upper case letter is the hardest read
***lines in data graphics should be thin (185)
***Choosing perpendicular intersections of lines of different weight, the heavier line should be a data measure (186)
* Manners of presenting (from the lecture)
** Research problem, examples of problem solutions
** Content: what the problem is, relevance, solution
** Dedicate 8 min of you presentation for audience to pre-read of the material
** Present the material as it was given for the pre-read. Nothing like repetition improves the understanding
** Credibility on speech: give the reasons to believe - documentation
** Conclude with question to personalize/particularize
Web Design
* "Information becomes the interface" - Basically don't clutter your interface except with the information the audience wants - Visual Explanations, pg. 146
== Reading Summaries==
* [[Scientific and engineering - Mobeen]]
* [[Financial Data - Elena]]
* [[Decision making Based on Evidence - Emily]]
