This morning, I came across a tweet linking to a National Geographic article on data visualization and eye candy, which I emailed to a few friends (when we want to carry on a more in-depth conversation Twitter just doesn’t cut it):
“Find a metaphor, start simple, and build up from there.”
One, who works at an economics research organization, replied with:
“We have lots of tools that allow relatively informed users to explore data and answer questions that they have, but few of our visualizations actually stick to a single story line. We’re trying to improve the balance of exploratory tools vs. simple, compelling stories.”
That’s highly similar to the approach often taken with interactive mapping interfaces – either attempting to duplicate desktop GIS functionality or show a particular facet of data with spatial attributes. Finding the balance between them is tricky. Generally, end users want to answer one or two questions though.
The trails web app I linked to recently – https://helenamontanamaps.org/Html5Viewer/?viewer=trails – is about as far as I’d ever go towards the GISFunc side of things anymore (there are a few gee-wiz, that’s cool features like mixed transparency for the base layers…but are they really necessary in most cases? No way).
http://mapbrief.com/2015/01/09/daring-to-build-a-citizen-centric-homepage-the-philadelphia-story/ is one of the best pieces I’ve read on user-focused functionality.
Incidentally, I read that NatGeo article on my phone and many of the visualizations were too small to be intelligible. For some reason, this one on landslides stood out to me as good on the phone (although on my desktop monitor the map background is barely visible):
A couple days ago, one of these correspondents sent me a link to a draft page showing all kinds of data related to load times, download sizes, CMSes used, and number of subscribers for a raft of news publications. I can’t share that page in its current state but will say that I wrote back encouraging him to make it way simpler. Just ’cause Tableau gives you a kitchen sink toolbox doesn’t mean you have to use it.
