d3.js

using python to generate static sites and having a front-end to do javascript things

movement towards static sites?
Pandoc: 
	written in Pascal and makefiles
	takes text as an input
	generic markup converter
markup and markdown to html

d3.js:
*evolved to a point where it’s very disconnected from the form you will show
*customizable
*short for data-driven documents
*good for fluid documents
*library that allows designers and developer to create visualisations of data in a web browser
*project led by Mike Bostock
*good at supporting interactive and live/changing data via transition and the subtle notion of a data join
*not SVG-specific
*not particularly suitable to drawing in an imperative style (for ex on an HTML canvas element)

web scraping=python
security errors with javascript?

use python to produce json documents and then you make a document that’s javascript


*like query, d3 uses selections instead of loops:
<script>
d3.selectAll(“a”).style(“color”,”pink”);
</script>

*introduces the notion of chaining:
the selection object when you tell it to do smth that function has an effect but it also returns itself; convention to do things but 
*d3 uses indentation cues 

**functions:
	*attr
	*style
	*text,html
	*append
	*classed
	*property
