And trying to find related content can also be difficult, depending on what data you’re looking for.
But data visualizations can make all of that much easier, allowing you to see the concepts that you’re learning about in a more interesting, and often more useful manner.
Below are 50 of the best data visualizations and tools for creating your own visualizations out there, covering everything from Digg activity to network connectivity to what’s currently happening on Twitter.
Music, Movies and Other Media
Narratives 2.0 visualizes music. Different music tracks are segmented into single channels that are then shown in a fan-like structure.
Liveplasma is a music and movie visualization app that aims to help you discover other musicians or movies you might enjoy. Type in the name of a band, artist, movie, director or actor and liveplasma will show you related people, bands or movies.
Tuneglue is another music visualization service. Just type any artist or band into the search box and hit enter. A circle comes up representing that band. You can then expand from there, clicking on any new additions after each expansion to expand further. By click on “releases” you can order their albums from Amazon.
MusicMap is similar to TuneGlue in its interface, but seems slightly more intuitive. Search for an artist or band and a list of albums will come up. Once you choose an album a circle pops up on the map. From there you can expand to get related albums, remove that album, or get more information.
Last.Forward is a downloadable, open-source tool to visualize any Last.fm user’s social network, including relationships between other users.
Fidg’t is a desktop app that uses Flickr and Last.fm tags to let you visualize your network and their tagging activities. You can see what your network’s predispositions are toward different tags and types of content.
Digg, Twitter, Delicious, and Flickr
Looks Del.icio.us is a collection of different Delicious bookmark visualizations. They’re created with a python-based graphics library and layout engine.
Arc is a product from Digg Labs that shows the latest Diggs, and the relationships between the users submitting and digging them. There are two different speed modes, the slower of which is great if you actually want to read the story headlines.
Stack is probably the most useful of the visualization offerings from Digg. Stories with the most recent activity load across the bottom of the screen and then ‘Diggs’ seemingly fall from the sky to land and create a real-time graph of what stories are popular. Whenever a ‘Digg’ hits a story stack, the title of the story is shown at the bottom of the screen, pushing previous stories down, and eventually off the screen.
Swarm has one of the cooler user interfaces of all the Digg Labs offerings, with stories and users flying around on the screen. When someone ‘diggs’ a story, they fly over to the circle representing the story itself and are briefly linked up to it. Hovering over a story or user shows its name and allows you to click. You can also download Swarm as a screensaver.
Research Chronology shows the relationships between one student’s research paths via Delicious bookmarks over the course of a semester. It’s an ongoing project and includes bookmarks for more than 270 websites.
TwittEarth shows live tweets from all over the world on a 3D globe. It’s a great visualization tool to see where tweets are coming from in real time and discover new people to follow. It’s also fascinating just to sit and watch.
Tag Galaxy lets you search for Flickr tags and have them shown visually in a mockup of a star system. Clicking on any planet (tag) within the first representation changes the image and recenters that tag as the star and pops up new related tags as planets. Clicking on the sun itself brings up a globe covered in images tagged as you’ve specified.
The Flickr Related Tag Browser allows you to search for a series of tags and see related tags. Clicking on a different tag brings up new related tags. You can zoom into the tag selected in the center of the screen by hovering and see images tagged with that word. It also gives a total image count and lets you browse by page.

The Hierarchical Structure of the Internet was a study that looks at how the Internet is organized, both in terms of structure and connectivity. It shows how the central core of the Internet is made up of about 80 core nodes, but that even if those nodes failed, 70% of the other nodes would still function via peer-to-peer connections.
Rootzmap—Mapping the Internet is a series of maps based on data sets provided by NASA and created by Philippe Bourcier. There are a number of different maps available.
Websites as Graphs shows the structure of different websites based on the tags used in their code in a color-coded map that grows on the screen as you watch. Tags are somewhat intuitive in their color-codes, with blue for links, red for tables, and gray for any tags not specifically given a color.
Schemaball visualizes SQL database schema. Relationships are shown based on foreign keys within tables. It’s capable of showing schemas with hundreds of different tables and relationships.
