Nothing but a Number

Over the next week you will create one poster every day. Each day, find a single number from a different subject area that interests you and spend your time thinking about how the scale of that value could be communicated formally. Create a visual representation using one of the seven…

Numeric Matrix / Half Matrix

matrix - any two dimensional set of numbers, colors, intensities, sized dots, or other glyphs. half matrix - where only half a matrix is shown, usually used for similarities, or where two items are being compared against one another (i.e. the D' table). Only half the matrix is needed…

heat map

a map that uses color or some other feature to show an additional dimension, for instance a weather map depicting bands of temperature.This is a heat map I modeled in Blender. It shows computer predictions of stable DNA strands. 1/15 different data visualizations I'm working on.' -Will…

DENDROGRAM

A dendrogram is a stacked tree that is shown connected to points, where the height of the branches show an additional variable. Often used to depict the stregnth of clusterings in a matrix. For a clustering example, suppose that five taxa (a to e) have been clustered by UPGMA based…

Box Plots

Invented by John Tukey, the Box Plot, also known as the box and whisker plot, is a two dimensional plot that shows a point and its first (and sometimes second) standard deviation. It is a useful depiction of the fact that data is often not simply discrete points, but ranges…

Tree/Graph

TreeGraphA graph has finite sets of vertices and edges. Vertices are otherwise referred to as nodes, and two of these are connected by an edge like shown in the above image. A tree has a set of nodes, but not necessarily edges. Instead, it has one specific node called the…

Linear and radial parallel coordinates

Linear parallel coordinatesParallel coordinates are a common way of visualizing high-dimensional geometry and analyzing multivariate data. To show a set of points in an n-dimensional space, a backdrop is drawn consisting of n parallel lines, typically vertical and equally spaced. A point in n-dimensional space is represented as a polyline…

Tree map

It uses rectangles to display hierarchical data. The color and size dimensions are correlated in some way with the tree structure. Its advantage is that it simultaneously show the big picture, comparisons of related items, and allow easy navigation to the details. However, it is really hard to get all…

Week 1

Assessment of student skills, levels, and interests What do you want to learn in this class? What sorts of data/information graphics work have you done previously? Any coding or stats experience? Introduction to course goals and expectations Intro talk Exercise: Catalog & Classify Create and publish a new post…

Retinal Variables

The most fundamental choice in any data visualization project is how your real-world values will be translated into marks on the page or screen. In this exercise we’ll be encoding an extremely simple data set repeatedly in order to exhaustively catalog the different ways a handful of numbers can…

Research Presentations

Each student will select a data visualization person, topic, theme, technology, etc. to thoroughly research and report on for the rest of the class. You will become an expert in this subject and explore some of the main ideas and concepts behind the research topic you've selected. Some questions to…

Policies

Academic Integrity PolicyAt Pratt, students, faculty, and staff do creative and original work. This is one of our community values. For Pratt to be a space where everyone can freely create, our community must adhere to the highest standards of academic integrity. Academic integrity at Pratt means using your own…

Syllabus

Charts and graphs have an indisputable aura of objectivity and yet, much like statistics, they have an immense power to either elucidate or mislead. What does it mean for an information graphic to be ‘honest’ with its data? And how can we as designers (and citizens) know when a representation…

Welcome to Ghost

Welcome, it's great to have you here. We know that first impressions are important, so we've populated your new site with some initial getting started posts that will help you get familiar with everything in no time.…

Creating a custom theme

Ghost comes with a beautiful default theme designed for publishers which can easily be adapted for most purposes, or you can build a custom theme to suit your needs.…
