This occurrence of the bi-annual corruption of the space-time continuum (i.e. changing to/from standard/daylight time) in the U.S. caused me to make a slight change to the code [from an older post](https://rud.is/b/2014/09/23/seeing-the-daylight-with-r/). The `daylight()` function now auto-discovers the date and location information (via [telize](http://www.telize.com/)) from the caller, which means all you have to do to… Continue reading
Junk Charts [adeptly noted and fixed](http://junkcharts.typepad.com/junk_charts/2015/10/is-it-worth-the-drama.html) this excessively stylized chart from the WSJ this week: Their take on it does reduce the ZOMGOSH WE ARE DOOMED! look and feel of the WSJ chart: But, we can further reduce the drama by using a more neutral color encoding _and_ encode both the # of outbreaks and… Continue reading
There was some chatter on the twitters this week about a relatively new D3-based charting library called [TauCharts](http://taucharts.com/) (also @taucharts). The API looked pretty clean and robust, so I started working on an htmlwidget for it and was quickly joined by the Widget Master himself, @timelyportfolio. TauCharts definitely has a “grammar of graphics” feel about… Continue reading
Nathaniel Smith and Stéfan van der Walt presented a new colormap (for Python) at SciPy 2015 called viridis. From the authors: The default colourmap in Matplotlib is the colourful rainbow-map called Jet, which is deficient in many ways: small changes in the data sometimes produce large perceptual differences and vice-versa; its lightness gradient is non-monotonic;… Continue reading
Poynter did a nice interactive piece on world population by income (i.e. “How Many Live on How Much, and Where”). I’m always on the lookout for optimized shapefiles and clean data (I’m teaching a data science certificate program starting this Fall) and the speed of the site load and the easy availability of the data… Continue reading
I’ve been slowly prodding the [metricsgraphics package](https://github.com/hrbrmstr/metricsgraphics/) towards a 1.0.0 release, but there are some rough edges that still need sorting out. One of them is the ability to handle passing in variables for the `x` & `y` accessor values (you _can_ pass in bare and quoted strings). This can now be achieved (in the… Continue reading
The recent announcement of the [start of egg rationing in the U.S.](http://www.washingtonpost.com/blogs/wonkblog/wp/2015/06/05/the-largest-grocer-in-the-texas-is-now-rationing-eggs/) made me curious enough about the avian flu outbreak to try to dig into the numbers a bit. I finally stumbled upon a [USDA site](http://www.aphis.usda.gov/wps/portal/aphis/ourfocus/animalhealth/sa_animal_disease_information/sa_avian_health/sa_detections_by_states/ct_ai_pacific_flyway/!ut/p/a1/lVPBkqIwEP2WOexpCxMBAY-oo6Kybo01q3JJNSGB1GCgSNTi7zcwe3CnZnQ3h1Sl-3X369cdlKADSiRcRA5aVBLK7p14ZLVd2sMJtqPFbvyMox-_5nGw8Z3t0jWAowHgL06I_47friOvi3_Bk-VsiHcO2qMEJVTqWhfoCHUhFKGV1ExqUoq0gab9hhWQ6twQXtGz6l8gxQlKUjAodXFryYRioBgRklfNqW_i3X0RIG_xGdOMdm5F0pYoDZqZ1FQTEKQGKrighJftFdqOX01Fho7c9iiAzS3HG6WWm2HbSnmAzYXxyA3AG1L-R487Df-TntNFuHT9jVHQDWwczUywP44xjrxH8b2eDzL0gHsj-1Bk8TwxReabn_56ZeP1CB0NSf9LFmMX7f5TtdXDtmYoib9z5YadQnYTT-PcVABdWN2s0eHuDry7b3agN3y2A-jw6Q4YfnlZpeZD7Ke3REKZOoEh0jDOGtYMikppdLher4OzymCQVxdUn15PgdMK6-0lwM7obR9ayTx_evoNPxBrVg!!/?1dmy&urile=wcm:path:/APHIS_Content_Library/SA_Our_Focus/SA_Animal_Health/SA_Animal_Disease_Information/SA_Avian_Health/SA_Detections_by_States/) that had an embedded HTML table of flock outbreak statistics by state, county and date (also flock type… Continue reading
I set aside a small bit of time to give [rbokeh](https://github.com/bokeh/rbokeh) a try and figured I’d share a small bit of code that shows how to make the “same” chart in both ggplot2 and rbokeh. #### What is Bokeh/rbokeh? rbokeh is an [htmlwidget](http://htmlwidgets.org) wrapper for the [Bokeh](http://bokeh.pydata.org/en/latest/) visualization library that has become quite popular in… Continue reading
