This question represents exactly the wrong way to reason about information displays. It begins by celebrating this week's technology rather than reasoning about the intellectual problem at hand. You will do better at information design if you first ask "What is the intellectual problem that this display is supposed to help with? What is the thinking task that this display will assist?" The answers to these questions will begin to specify the kinds of evidence and displays that you need.

The computer screen is not very good at displaying a big historical timeline; the low typographic resolution of the screen forces viewers to scroll endlessly through century after century (and, even worse, horizontal scrolling). Perhaps, on the computer screen, time should flow vertically, with events described by lines of horizontal type at each date. On the other hand, it is nice to maintain the time-flowing-left-to-right convention used in excellent timelines (printed, lots of overlapping events, hundreds of events).

For a competent timeline shown on a computer screen, see Google's summary of the searches of 2001 at https://www.google.com/press/timeline.html You should find some classic examples of timelines (regardless of the method of display!) and think hard about those examples.

For an excellent timeline, see "Graph of the Day: New York Times, February 6, 2002," a thread in Ask E.T.:

Recently the site Accelenation published a timeline of "7 years of 3d graphics," showing the history of 3d accelerator cards in the PC industry.

I think they did a very good job. It is clear, easy to read, and oriented vertically for easier scrolling.

They even managed to put their site's name as a watermark that is unobtrusive, yet discourages digital plagerism.

I'm advocating a very pared-down but functional text-only timeline-format that has the advantage of supporting hundreds of inline links. My most extreme example is this timeline of James Joyce's life, but if you explore my site you'll find a hundred shorter examples.

My ideal is that each item on a timeline should offer at least one useful link, as a 'text button' at the end. [theory]

To break up the long blocks of text I arbitrarily skip a line every screen's worth or so, or I insert lively pullquotes as short indented texts using BLOCKQUOTE.

Google Timeline 2002

See the Google Zeitgeist Timeline 2002 https://www.google.com/press/timeline2002.html.

Google's widespread international use is interesting, as well as the growth of languages other than English on the internet.

The horizontal scrolling for the timeline continues to work well.

-- Edward Tufte

While the horizontal scrolling works, if the design and scrolling were vertical, wheelmouse functiality would make viewing easier. Seems the same data could be presented vertically.

My wife and I are expecting and did a typical search on the web for name ideas. I ran across this site and thought I would share it with this forum. What are the thoughts on interactive data analysis? ... being able to manipulate the data and presentation based on simple filtering. Here is the example, though not as complex as the question.

Thanks, Jason

P.S. - I enjoyed your class in Scottsdale, AZ

-- Jason Edleman (email)

The babynamewizard is fascinatingly addictive. I suspect that it is from a US source and does not reflect the same distributions as names in the UK. Also, I would be interested to learn the sample size and the provenance generally. A small point is that the search facility at the top left was not immediately obvious: the legend underneath it disappears after the full display has loaded. Otherwise though it is recommended as five minutes fun for any browser of this forum.

Sparklines?

-- Edward Tufte

I've enjoyed the Timelines in http://www.eternalegypt.org Time flows vertically and it is possible to select coarse to fine scales. Selecting specific eras brings up information on artifacts from that period.

For the big historical picture, see Daniel Rosenberg's The Trouble with Timelines, and Sasha Archibald & Daniel Rosenberg's Timeline of Timelines (Cabinet magazine, Spring 2004). Among the images on the latter page we find some classics, such as Minard's 1869 chart of French casualties in Napoleon's Russian campaign, familiar to all Tufte fans. But there are also some surprises, including a barely legible yet intriguing JPEG of a chart from Joseph Mede's Key of the Revelation (1626), the remarkable 54-foot Carte chronologique by Jacques Barbeu-Duborg (1753), and the Diagram of the Causes of Mortality by Florence Nightingale (1857). Given the poor reproduction quality, these images are difficult to read clearly. Luckily, Cabinet also appears in paper form.

Timelines in The 9/11 Report: The Graphic Adaptation

Sid Jacobson and Ernie Colon's graphic adaptation of the 9/11 Commission Report begins with four timelines comparing the four hijacked planes on Sept. 11. You can view the entire book online at Slate. The graphics present pretty strong visual arguments for the failure of communication on that day (see especially page 8 of section 1 in the Slate version).

Some of you may be interested in this application set from some of the folks at MIT:

http://simile.mit.edu/timeline/

It is a set of JavaScripts that allow you to build a customizable timeline with link(s) to XML, JSON, etc. datasets.

It is still somewhat "do-it-yourself" but it seems that it may be useful for generating live timelines/progress charts.

The folks that are developing it are also very good/prompt in answering questions.

The ultimate "timeline"

The human genome has, at the highest resolution, some 3 billion letters. There are, however, important features that become relevant when you examine the data at different resolutions. So from the perspective of presenting the data on a screen, presenting the genome is very much like presenting a timeline.

Anyone (biologist or otherwise) can appreciate the features of these two genome browsers. Click around on the options, zoom in and out...

Google Finance shows financial data in a dynamic chart with a timeline across the bottom.

The timeline has a sliding, resizable marker of the slice of data shown above. Links atop the chart "zoom" to other slices. Moving the cursor left and right on the chart allows fine-grained review of the price over time.

Clunky Google Finance

The Google Finance material linked immediately above needs work. It looks like it was put together with a shovel.

The table at the top is fine but too thin. The graphic is low-resolution, and the lettercode buttons are too big. The links at the right are twitchy, moving around too much as their motion catches the eye. Moving the scroller to the left leads to chaos.

The information is alas segregated by its mode of production: a separate table, another place for words, and a third area for graphics. Evidence doesn't care what it is.

Graphics on automatic pilot are usually going to have problems since their design cannot be customized to one particular data set. But there is a long history of displays of financial data of this sort--and many of the competing displays are better.

In terms of comparative grades, Google News gets an A; this Google Finance architecture a C-.

It may be that there was too much technology-driven design (or perhaps hubris) and not enough financial insight engaged in creating the architecture.

-- Edward Tufte

This may be straying slightly off-topic, but a comment above caught my attention.

"Graphics on automatic pilot are always going to have problems since their design cannot be customized to one particular data set."

Are you making a statement about the current state-of-the-art in information design, or about the inherent limitations of information design? Many things can now be accomplished by artificial intelligence that were once believed impossible.

For example, choice of scale can be much more intelligently programmed than what is currently available in most business graphics packages, but this is the state-of-the-art and not an inherent limitation in information design. The sparklines threads have evoked some elegant rules-of-thumb for scale that could easily be encoded into a graphics package.

Newer Daniel Rosenburg collection of timelines

Daniel Rosenberg, along with Anthony Grafton, has published another collection of timelines in "Cartographies of Time: a history of the timeline". More information can be found on the Princeton Architectural Press's website.

-- Ed Manlove (email)

I followed Ed Manlove's suggestion regarding the Cartographies of Time book, really great book! I encourage everyone to check it out. There are some great examples of what has been attempted in the past.

More recently I have been interested in timelines that show all of history- literally from the Big Bang to the present. Here are two, the first is static, the second is interactive.

1. Big History Project

2. Chronozoom

Facebook timeline

Facebook, in my opinion, created a decent approach for web viewing of a timeline. Its optimized to show a good amount of information while maintaining the timeline metaphor.
