Thanks to a nice call-out post link on Flowing Data in my RSS feeds this morning, I found Naomi Robbins’ Effective Graphs Forbes blog, perused the archives a bit and came across her post on arrow charts. She presented a nice comparison between (ugh) pie charts, arrow charts and slopegraphs. Sadly, both the NPR slopegraph… Continue reading

Slopegraphs in Python – Failed States Index (Part 1)
The Fund For Peace (FFP) and Foreign Policy jointly released the 2012 version of the “failed states index” (FSI). From the FFP site, the FSI: …focuses on the indicators of risk and is based on thousands of articles and reports that are processed by our CAST Software from electronically available sources. I read it every… Continue reading
Slopegraphs in Python – Gratuitous Raphaël Animations
UPDATE: It seems my use of <script async> optimization for Raphaël busted the inline slopegraph generation. Will work on tweaking the example posts to wait for Raphaël to load when I get some time. So, I had to alter this to start after a user interaction. It loaded fine as a static, local page but… Continue reading
Slopegraphs in Python – Formatting Tweaks
There were enough eye-catching glitches in the experimental javascript support and the ugly large-number display in the spam example post that I felt compelled to make a couple formatting tweaks in the code. I also didn’t have time to do “real” work on the codebase this weekend. So, along with spacing adjustments, there’s now an… Continue reading
Slopegraphs Everywhere
Not much progress over the weekend on my latest obsession (been busy enjoying some non-rainy days here in Maine). So, here are some other slopegraph implementations/resources I’ve found through mining the internets: A spiffy editable javascript implementation defensive slopegraphs slopegraphs in tableau an interesting d3 implementation another javascript implementation an R table-graph (original name for… Continue reading
Slopegraphs in Python – Experimental Raphaël Support
In preparation for the upcoming 1.0 release and with the hopes of laying a foundation for more interactive slopegraphs, I threw together some rudimentary output support over lunch today for Raphaël, which means that all you have to do is generate a new slopegraph with the “js” output type and include the salient portions of… Continue reading
Slopegraphs in Python – Log Scales & Spam Data Analysis
Given the focus on actual development of the PySlopegraph tool in most of the blog posts of late, folks may be wondering why an infosec/inforisk guy is obsessing so much on a tool and not talking security. Besides the fixation on filling a void and promoting an underused visualization tool, I do believe there is… Continue reading
Slopegraphs in Python – Exploring Binning/Rounding
One of the last items for the 1.0 release is support for multiple columns of data. That will require some additional refactoring, so I’ve been procrastinating by exploring the recent “fudging” discovery. Despite claims to the contrary on other sites, there are more folks playing with slopegraphs than you might imagine. The inspiration for today’s… Continue reading
