Revisiting javascript and D3

Ok, so this is a bit of a blast from the past.

There are a couple of Code Club students that are interested in HTML and generally manipulating web content.

I've agreed to have a look at Javascript and try to organise a few lessons.

Revising my old D3 code skills....

Some things to think about:


Code can be run on https://jsfiddle.net
This gives an online play area...
Three windows with HTML, CSS and Javascript
and then a result window.

JQuery Biolerplate can be added.
D3 can be added as a library here:

Currently No_Library but easy to add stuff...


There are some key things to understand:

• <div></div>
• var
• chaining

Some nice simple tutorial...

Probably worth encouraging students to work through both of the HTML projects or at least the one with Javascript...

Observable might be an interesting tool but probably not right now...

Other Javascript libraries are available:

N.B. The trinket for the the Code Club project gives the answer - NOT good!
