Rachel,
I write this with the intent to create the most seamless transition possible from me working with data visualizations to not working with data visualizations, and to help integrate what I’ve created into your future powerpoint slides, and lesson plans.
Fortunately, all the visualizations and graphs I’ve been working on are sourced with html code, which means they will be easily embedded onto any web based page you need them to be. I believe it would be best to use the iframe plugin in most instances to do this most effectively, which instructions are posted for here: http://epress.trincoll.edu/dataviz/chapter/embed-iframe/
I believe all URL’s for my visualizations are openly available as well, and from this can be simply embedded via iframe.
Additionally, since all the html code for my visualizations are publicly available, they can be easily forked, edited and hosted to update, or change for any other applicable lesson plans. A simple intuitive version as to how one may edit an html file to insert appropriate data can be found here: https://github.com/JackDougherty/gviz-scatter-series/blob/master/index.html,(lines beginning with // represent instructions as to how to properly modify).
I hope to meet with you in the next few weeks to finalize how to properly meet your future data visualization needs. That being said, I hope the instructions presented here are a good start.
Best,
Ben
