Creating color systems for data visualization

Posted on February 19, 2018April 17, 2019 by Erica

We have been working on a product re-design at work lately, and I’ve been thinking a lot about what goes into making a good color system for analytical applications. The purpose of color in our application UI can be broken down into a few distinct (and often competing) themes: Color to direct attention. Color can…

Gunn Color Lab, Part II

Posted on January 22, 2018April 12, 2019 by Erica

In the last post, I wrote about a color picker application that I’ve been playing with as an evening project lately. I’m going to be building some fairly demanding color palettes over the next few months at work, and wanted a tool that would support iteration and cut some of the time out of the…

Gunn Color Lab

Posted on January 22, 2018 by Erica

Having the ability to make your own tools is one of the best things about programming. Recently, I’ve been working on color palettes for a data visualization application at work, and needed a better (and less manual) way than mocking up a bunch of alternatives in Illustrator. I wanted a few very specific things from…

VizTech2017: Teaching d3 and data visualization

Posted on January 14, 2018 by Erica

My course in d3 and data visualization for the Northeastern graduate program was recently highlighted on their blog. I was extremely proud of the students’ final projects; they did a great job of going from zero to some pretty amazing webpages in just a few short weeks. Course syllabus with links to weekly student work…

GROW proposal: Visualizing soil moisture data

Posted on July 17, 2017April 12, 2019 by Erica

Back in May, I submitted a proposal to the VERTIGO STARTS initiative for an artist residency with the GROW project in Scotland. The GROW project disburses soil moisture sensors to citizen scientists in Europe, who then place the sensors in the ground where they live. The sensors automatically report information on soil moisture, nutrient levels…

ThesisSite: Thinking about detail and levels of scale

Posted on March 15, 2017April 12, 2019 by Erica

I thought it would be helpful to take a step back and look at the birds-eye view of the website content as I close in on feature lock over the next couple of weeks. I wanted to make sure that the narratives are balanced, that the level of detail is where I want it, that…

ThesisSite: Cleaning up Land Use Layout

Posted on March 14, 2017April 12, 2019 by Erica

I spent most of last week roughing out the code structure for the land use data. The broad-strokes development phase can be a lot of fun, because things come together so quickly, and you don’t have to focus on all of the details. Once it’s mostly-functioning and I can see where it needs to go,…

ThesisSite: Integrating Land Use Data, Part II

Posted on March 9, 2017April 12, 2019 by Erica

I’ve been working away on the last major data component of the thesis site this week. In the past couple of days, I’ve been updating the front page (of this module), to include all of the data. I haven’t taken the time sliders out of the page yet, but definitely plan to stick with a…

Designing a memorial booklet

Posted on March 6, 2017April 21, 2024 by Erica

When my uncle passed away unexpectedly last October, I took on the responsibility of organizing a memorial service to honor his life. I wanted something that would capture his irreverent spirit, and that would honor his artwork as well. For the service itself, I designed a simple booklet with poems and readings to guide the service, and…

DesignSynthesis: Site sign

Posted on March 6, 2017 by Erica

We’ve also been working on designing a site sign for the World Heritage project in my design synthesis class. The sign needs to show 100-150 words of text set in 7 different languages; the official languages of the UN, and the language for the country that the site is located in. My first sketch focused…
