Topic 2 - Utilities
Utility functions d3.json(path, callback) d3.csv(path, accessor, callback) d3.html(path, callback) d3.text(path,
type, callback) d3.xhr() …
Utility functions d3.min(array) d3.max(array) d3.sum(array) d3.mean(array) d3.median(array) d3.random.normal d3.set set.has
set.forEach d3.map map.has map.forEach d3.transition d3.svg
Scale functions d3.scale.linear().domain(array).range(array) radius = d3.scale.linear() .domain([d3.min(data), d3.max(data)]) .range([“#f00”,”#00f”]) !
ticks = radius.ticks(20); d3.scale.pow().exponent(3).domain(array).range(array) d3.scale.log().domain(array).range(array)

Topic 3 - Layout
Pack Layout
Pack Layout nodes = d3.layout.pack().size([w,h]) .nodes(data) structure of data: {
value: ?, children: [ ] } { value: ?, children: [ ], parent, depth, x, y, r }
{ parent: null, children: [ {value: 3}, {value: 1}, {value:
4}, {value: 1}, {value: 5}, ………… ] } c = data.map( function(d) { return {value: d}; } ); ! root = { children: c }
{ parent: null, children: [ {value: 3}, {value: 1}, {value:
4}, {value: 1}, {value: 5}, ………… ] } [ {value:0,depth: 0, x:…, y:…, r:…}, {value:3,depth: 1, x:…, y:…, r:…}, {value:1,depth: 1, x:…, y:…, r:…}, {value:4,depth: 1, x:…, y:…, r:…}, …… ]
Pack Layout d3.layout.pack() .sort(function(a,b) {…}) .padding(5) .size([w,h]) .nodes(data) ! d3.layout.pack().links(nodes)
{ source: <node>, target: <node> }
Partition Layout d3.layout.partition() .sort(function(a,b) {…}) .size([w,h]) .nodes(data) ! d3.layout.partition().links(data) {
value: ?, children: [], parent, depth, x, y, r, dx, dy }
arc = d3.svg.arc() .startAngle(function(d) { return d.x; }).endAngle(function(d) { return
d.x + d.dx; }).innerRadius(function(d) { return Math.sqrt(d.y); }).outerRadius(function(d) { return Math.sqrt(d.y + d.dy); }); Use d3.svg.arc * also check the pie layout
Force Layout d3.layout.force() .size() .gravity() .charge() .friction() .nodes() .start() d3.on(“tick”,
callback) [{…},{…},…] [ {…, x:…, y:…}, {…, x:…, y:…}, {…, x:…, y:…}, … ]
data = [1,2,3,4].map(function(d) { return {v:d}; }); ! force =
d3.layout.force().nodes(data); ! force.on(“tick”, function() { d3.selectAll(“…”).attr({ x: function(d) { return d.x; }, y: function(d) { return d.y; }, … }); force.start();
Cluster Layout d3.layout.cluster() .sort(function(a,b) {…}) .size([w,h]) .nodes(data) ! d3.layout.cluster().links(data) {
value: ?, children: [], parent, depth, x, y }
