Some interesting visualization/animations in this one, but want to highlight this issue:
That's not so nonsensical when you view gender as a spectrum, Ms Campbell.

Yes, but is it a linear scale?

Or should we use a log scale?

I saw a nice graph of the current poll results for the presidential election, published by the NYT, but I can't find it now. So I'll link to something similar and describe it. Basically, it was the map below, but with each state colored based on recent polls. So some states were dark/medium/light red or blue, or yellow for states that were really close. It avoids the "vomit" look by being a set of tidy squares. The geography is familiar enough that you can see the nation, despite the distortion. You could glance at this map and have a sense of what Clinton's lead is right now, and what states were going to matter.

And here's an article that talks a little about it.

Communicating with data – timelines

FT visualisation experts turn to the past to solve a complex chart problem

Anyone faced with a design challenge will recognise “the feeling” — something is not quite right, yet it is difficult to put your finger on the problem.

Here is an example from a story recently featured in the FT: emerging- market populations are expected to age more rapidly than those in developed countries. The figures alone are compelling: France is expected to take 157 years (from 1865 to 2022) to triple the proportion of its population aged over 65, from 7 per cent to 21 per cent; for China, the equivalent period is likely to be just 34 years (from 2001 to 2035).



Quote:

But, to me, this approach generates “the feeling” — and further scrutiny reveals specific problems. A reader must work hard to memorise the date information next to the country labels to work out if there is a relationship between the start date and the length of time taken for the population to age. The chart is clearly not ideal, but how do we improve it?
.....

One pioneer from the pre-computer era, whose work was of towering significance, was Joseph Priestley, an 18th century polymath. Famous in his own lifetime for the invention of soda water, and with at least a partial claim to the discovery of oxygen (or “dephlogisticated air” as he preferred to call it), Priestley’s popular writings covered theology, politics, science and history. He was also a passionate teacher and as well as writing essays on approaches to education, he prepared materials to aid students.


Quote:
So it was to Priestley’s timelines that I turned for inspiration to solve our puzzle about emerging markets and their populations. Showing date and duration together was exactly the visualisation challenge I faced. By adapting the horizontal axis of the chart to show the progress of time rather than simple duration in years (a subtle but important distinction), we can move the bars from our chart into a chronological format, and arrange them in order of when they first hit 7 per cent of the population being 65 or over.


Quote:

I did not draw this graphic by hand. And yet it is not a chart type offered very often by today’s software chart wizards. It was produced using d3.js, an open-source code-based visualisation library. It has no wizard. Simply put, the library allows someone to make use of what computers are good at (which is handling data and using it to repetitively draw precise geometry — based on instructions you give it). But it keeps the human in charge.

As Mike Bostock, creator of d3.js, has said: “I wanted something that gave the designer greater control over the output — the kind of control that the early practitioners [like Playfair] had because they did things by hand.”

Learning how to code can be daunting — but the rewards of using d3.js are significant. And the good thing with computer code is that it is shareable and reusable. You can access the code I wrote to produce a simple Priestley-style timeline on the code-sharing website GitHub. Alternatively, try sketching the design of your next killer chart on paper first (or if you are an economist such as Arthur Laffer, the back of a napkin) — the feeling of escaping the wizard can be liberating.

Hmm, I'm pretty sure I could have drawn that chart in excel. I'm not a huge fan of excel's chart-producing abilities, but this isn't the anti-excel poster child.

I'm thinking I could possibly produce that chart on my phone, like you did this post, Sir.
