I’m part of a group that’s trying to take a deep dive into our courses using “learning analytics”. My contribution is largely the technology side of it and its time to generate some pretty pictures. The following is a summary of some playing around with D3.js and ended up with some success with Plot.ly.
Example – box plots
Toe in the water time, can I get an example working. Start with box plots as I’ve got some data that could fit with that.
Rough process should be something like.
- Set up some space on the local web server.
- Install the library.
- Get the example working.
- Modify the example for my data
Step #4 is a bit harder given that I don’t yet grok the d3 model.
Work through some tutorials
Starting with bar charts.
So some jQuery like basics: selections, selectors, method chaining.
Appears joins might be the most challenging of the concepts.
data space (domain) -> display space (range)
Mmm, d3.js is too low level for current needs.
Does appear to be a big project.
Ohh nice. The example looks very appropriate.
Bit of data wrangling and the following is produced.
