Some quick D3 notes:

Selections

d3.select( element );
d3.select( node );
d3.selectAll( elements );
d3.selectAll( nodes );

HTML

d3.select( element ).text( 'Changes the text' );
d3.select( element ).html( '<span>Changes the <strong>HTML</strong></span>' );
d3.select( element ).append( 'div' ).html( '<span>Appends a div with this HTML</span>' );
d3.select( element ).insert( 'span', ':nth-child(3)' ).html( 'Insert a span @ <em>nth-child(3)</em>' );
d3.select( element ).remove();

CSS

d3.select( element ).attr( 'class', 'highlight' ); // changes the class to highlight
d3.select( element ).classed( 'highlight', true ); // ADDS the class highlight to the previous class list (toggling)
d3.select( element ).classed({ 'highlight': true, 'item': false, 'bigger': true }); // object passing handles multiple classes
d3.select( element ).style({ 'backgroundColor': '#268bd2', 'color': '#eee8d5' }); // pass object to control CSS as well

DOM

d3.selectAll( elements ).data( [true] ).style( 'background', '#268bd2' ); // applies to first element (data array binds to elements in order)
d3.selectAll( elements ).data( myStyles ).style( 'background', myStyles[0] ); // same as above, but passing in an array with the value
d3.selectAll( elements ).data( myStyles ).style( 'background', function(d) { return d; } ); // same as above, using multiple array values
d3.selectAll( elements ).data( myStyles ).style({ 'color': 'white', 'background': function(d) { return d; } }); // same as above, using an object to change multiple values

// Same as above, passing in an array of objects
var myStyles = [{ width: 200, color: '#268bd2' }, { width: 300, color: '#eee8d5' }];
d3.selectAll( elements ).data( myStyles ).style({ 
  'color': 'white',
  'background': function(d) { return d.color; },
  'width': function(d) { return d.width; }
});

.enter()

// Same as above, but enter() appends a bunch of divs into a temporary placeholder
// so you must selectAll .item's after selecting the #chart to append them back in to #chart
// The selectAll( '.item' ) command is connected with the .append( 'div' ) with a class 'item'
var myStyles = [{ width: 200, name: 'Aaron', color: '#268bd2' }, { width: 300, name: 'Sarah', color: '#eee8d5' }];
d3.select( #chart ).selectAll( '.item' )
  .data( myStyles )
  .enter().append( 'div' )
  .classed( 'item', true )
  .text( function(d) { return d.name; })
  .style({ 
    'color': 'white',
    'background': function(d) { return d.color; },
    'width': function(d) { return d.width; }
  });

SVG

Ref: https://developer.mozilla.org/en-US/docs/Web/SVG/

<svg width="600" height="400" style="background: #93a1a1"></svg>
<rect x="250" y="150" width="100" height="100" style="fill: #c61c6f" />
<circle cx="300" cy="200" r="50" style="fill: #840043" />
<text x="10" y="390" font-family="sans-serif" font-size="24" fill="white">SVG Graphics</text>
<g id="group" class="triangle"><polyline points="10 35, 30 10, 50 35" style="fill: #f7b330" /></g>
<use xlink:href="#group" x="30" y="0" />

SVG with D3

d3.select( '#chart' ).append( 'svg' ).attr( 'width', 600 ).attr( 'height', 400 ).style( 'background', '#93a1a1' ); // same as above
d3.select( 'svg' ).append( 'rect' ).attr( 'x', 250 ).attr( 'y', 150 ).attr( 'width', 100 ).attr( 'height', 100 ).style( 'fill', '#840043' ); // same as above

D3 Scales

  • Quantitative (numbers) aka like <ul> lists (order doesn't matter)
  • Ordinal (names, categories) aka like <ol> lists (order matters)
  • Time (times, dates)
