These are the materials for my workshop at Strata San Jose 2015 as well as resources and next steps. Videos of the workshop can be found here.
We will be using the following two tools to works through these exercises:
- bl.ocks.org: D3.js Gist renderer and online community
- Building Blocks: In-browser interactive D3.js bl.ock editor
I would love your feedback on the materials either on the Q&A forum (Google Group) or in the Github issues.
And please do not hesitate to reach out to me directly via email at jondinu@gmail.com or over twitter @clearspandex
Throughout this workshop, you will learn how to make this animated and interactive line plot of temperature over time in Noe Valley.
- Part 1: Multiple line chart of Shanghai vs. Bangalore pollution levels created with dimple
- Part 2: Line chart of Shanghai pollution levels over time created with D3.js
- Part 3 (you are here 👇): Interactive animated line chart with color gradient of Noe Valley (SF neighborhood) daily temperature series over time.
The data is from the Data Canvas project, which is sponsored by Gray Area, swissnex San Francisco, and Lift. It contains data from 14 sensors in 7 cities which collect and stream information about their environment (temperature, dust, pollution, humidity, light, etc.).
You an access a bulk download of all the data (100+ MB) here. You can also download samples or access the stream through the API (details on the data page).
There are 4 different granularities of measurement. Files ending in:
*-5md.csv
: measurements every 5 minutes for a day*-1hd.csv
: measurements every 1 hour for a day*-6hw.csv
: measurements every 6 hours for a weeknoevalley.csv (or grapealope.csv)
: entire history of the sensor near Noe Valley at 10 second resolution
The files are comma separated with headers and 8 fields:
timestamp | city | temperature | light | airquality_raw | sound | humidity | dust |
