Tools

Visualization Cheatsheets

• Data Viz Project by Ferdio
• Visual Vocabulary by Financial Times
• Chart Choser by Juice Analytics
• Ggplot2 Cheatsheet – Cheatsheet for ggplot2 (see below)

Visualization Toolkits

• D3 – JavaScript library for data-driven DOM manipulation, interaction and animation. Includes utilities for visualization techniques and SVG generation.
• Vega – Declarative language for representing visualizations. Vega will parse a visualization specification to produce a JavaScript-based visualization, using either HTML Canvas or SVG rendering. Vega is particularly useful for creating programs that produce visualizations as output.
• Vega-Lite – High-level visualization grammar that compiles concise specifications to full Vega specifications.
• Processing or p5.js – Java-like graphics and interaction language and IDE. Processing has a strong user community with many examples. p5.js is a sister project for JavaScript.
• Leaflet – Open-Source mapping library

Visualization Tools

• Tableau for Students – Free version of Tableau for students
• Tableau Public – Free version of Tableau for publishing on the web

Data Literacy Resources (Fall semester 2019)

Slides

• Theory Part I

General / good reads

• «The world’s most valuable resource is no longer oil, but data» vs. «Data is not the new oil»

• Data Scientist: The Sexiest Job of the 21st Century

Data quality

• The Quartz Guide To Bad Data
• Tidy Data – although the principle of tidy data stems from an R developer and the examples in this document are made in R, "tidy data" is a very valuable standard that you should achieve when working with data. Once your data is "tidy", visualization in R (or in any other language / framework) becomes easier. You can also look at the more formal and less R-heavy scientific paper.
  

Data formats / conversions

• http://www.convertcsv.com for converting data from a myriad of formats into others, e.g. from CSV to JSON.
  
• https://json-csv.com/ Another pretty good JSON-to-CSV-converter.
• http://www.reformattext.com for formatting text files and extracting information out of them.
  
• https://jsonformatter.curiousconcept.com/ for validating and formatting JSON data.
• An introduction to APIs
• How to use APIs with Python – The normal way of working with APIs is via a programming language. Python lends itself to communicating with many APIs, so once you know a bit of Python, this interactive course might be good for you.

Regex

• https://regexr.com/: Interactively test and learn Regex
• This tutorial doesn't look too bad: Learn Regex the Easy Way

Geospatial data

• An overview of common spatial data formats
• QGIS is an open source geographical information system and a good option for working with geodata on a non-regular basis (e.g. to look at some data or to compute areas of some regions). This tutorial collection will introduce you to it.
• geojson.io can be used to quickly visualize GeoJSON. Mapshaper can be used to generalize geometries and reduce file size, and it can convert between different file formats.
• ogr2ogr (and ogrinfo) are two very helpful CLI tools – just google for some tutorials!
• https://tools.retorte.ch/map/: Convert coordinates into/from the Swiss projection system.
• Municipal boundaries and districts of Swiss cities by the BFS. Jeremy Stucki (former IAD student) has processed these and other data into TopoJSON (easier to use for web applications).

Working with the CLI

The command line interface (CLI, often referred to as "shell" or "terminal") is a very powerful tool, and each operating system has one. Working with the CLI is easiest on Linux and Mac, and they are both similar since they are both based on Unix. I really recommend getting to know the 101 of working with the terminal, e.g. through this tutorial. Here are some more tips for working with data on the CLI. This Twitter account gives useful and sometimes funny tips on how to make the most of the terminal.

Data processing in R

• Data Analysis with R: Recent and good introduction, no prior knowledge needed
• rddj.info: Resources for doing data journalism with R
• Datacamp.com: Good, beginner-friendly and interactive courses on R (and Python).
