AC-D3 / AC-D3

Javascript Library for building Audiovisual Charts in D3

AC-D3 is a Javascript Library for building Audiovisual Charts in D3.

• Build predefined visualizations
• Use AC-D3 methods to add audiovisual elements to your D3 visualization

Installation

---

$ npm install ac-d3 --save

Using AC-D3

---

HTML

1. Create div with specific ID (Used in config object later)

<div id='vis1'></div>

Javascript

1. Require in library

const acd3 = require('ac-d3');

2. Create data array

Bubble Chart:

Key	Value datatype	Note
src	string	Accepts paths to HTML5
scalingParameter	number	Used to determine the relative size of each bubble.
v_id	string	Must be unique for each video.
type	string	Either 'video' (for direct URL path), 'vimeo', or 'youtube'.

const bubbleChartData = [
      {
        "src": 'https://www.youtube.com/embed/F-eMt3SrfFU',
        "scalingParameter": 36,
        "v_id": "vid1",
        "type": "youtube"
    },
    {
        "src": "https://player.vimeo.com/video/12868296",
        "scalingParameter": 12,
        "v_id": "vid2",
        "type": "vimeo"
    },
    {
        "src": "http://upload.wikimedia.org/wikipedia/commons/7/79/Big_Buck_Bunny_small.ogv",
        "scalingParameter": 24,
        "v_id": "vid3",
        "type": "video"
    }]

Bubble Scatter Chart:

Key	Value datatype	Note
src	string	Accepts paths to HTML5
v_id	string	Must be unique for each video.
type	string	Either 'video' (for direct URL path), 'vimeo', or 'youtube'.
x	number or date string	Used to determine the x position of the center of bubble.
y	number or date string	Used to determine the y position of the center of bubble.
r	number or date string	Used to determine the relative size of each bubble.

const bubbleScatterChartData = [
      {
        "src": 'https://www.youtube.com/embed/F-eMt3SrfFU',
        "v_id": "vid4",
        "type": "youtube",
        "x": "18-Dec-09",
        "y": 425000000,
        "r": 2783918982
    },
    {
        "src": "https://player.vimeo.com/video/12868296",
        "v_id": "vid5",
        "type": "vimeo",
        "x": "24-May-07",
        "y": 306000000,
        "r": 2058662225
    },
    {
        "src": "http://upload.wikimedia.org/wikipedia/commons/7/79/Big_Buck_Bunny_small.ogv",
        "v_id": "vid6",
        "type": "video",
        "x": "6-Nov-15",
        "y": 425000000,
        "r": 2783918982
    }]

3. Create config object

Bubble Chart Config Options:

Key	Value datatype	Note
chartType	string	Type of chart to create (current options are 'bubble' and 'bubbleScatter')
htmlAnchorID	string	ID of the div where AC-D3 will append the visualization
diameter	number	Overall diameter of the visualization in pixels
zoom	number	Zoom level of each of the videos
resolutionThresholds	array	This sets the bounds for which video resolution to use depending on height of the video (in pixels)
autoplay	boolean	This specifies whether the videos will begin playing automatically or not
loop	boolean	This specifies whether videos will start over again, every time it is finished
onDoubleClick	string	This specifies which event handler to invoke on dblclick (current options are 'openNewWindow', a function that opens the video in a new window, and 'expandBubble', a function that expands the size of the bubbe to fill the entire visualization)

const bubbleConfig = {
  chartType: 'bubble',
  htmlAnchorID: 'vis1',
  diameter: 600,
  zoom: 1.5,
  resolutionThresholds: [250, 500],
  autoplay: false,
  loop: false,
  onDoubleClick: 'expandBubble'
}

Bubble Scatter Chart Config Options:

Key	Value datatype	Note
chartType	string	Type of chart to create (current options are 'bubble' and 'bubbleScatter')
htmlAnchorID	string	ID of the div where AC-D3 will append the visualization
height	number	Overall height of the visualization in pixels
width	number	Overall width of the visualization in pixels
zoom	number	Zoom level of each of the videos
resolutionThresholds	array	This sets the bounds for which video resolution to use depending on height of the video (in pixels)
autoplay	boolean	This specifies whether the videos will begin playing automatically or not
loop	boolean	This specifies whether videos will start over again, every time it is finished
onDoubleClick	string	This specifies which event handler to invoke on dblclick (current options are 'openNewWindow', a function that opens the video in a new window, and 'expandBubble', a function that expands the size of the bubbe to fill the entire visualization)
dateFormat	string	This specifies the date format used
xIsDate	boolean	This specifies whether the data for the x position is a date
yIsDate	boolean	This specifies whether the data for the y position is a date
rIsDate	boolean	This specifies whether the data for the r dimension is a date
plottableAreaMargin	object	See example and diagram below
plottableAreaPadding	object	See example and diagram below
rLimits	object	See example and diagram below

const bubbleScatterConfig = {
  chartType: 'bubbleScatter',
  htmlAnchorID: 'vis2',
  height: 600,
  height: 900,
  zoom: 1.5,
  resolutionThresholds: [250, 500],
  autoplay: false,
  loop: false,
  onDoubleClick: 'openNewWindow',
  dateFormat: '%d-%b-%y',
  xIsDate: true,
  yIsDate: false,
  rIsDate: false,
  plottableAreaMargin: { top: 0, right: 0, bottom: 30, left: 65 },
  plottableAreaPadding: { top: 120, right: 100, bottom: 80, left: 60 },
  rLimits: { lower: 20, upper: 120 }
}

4) Create a new chart instance and invoke the createBubbleChart or createBubbleScatterChart method

const chart1 = new acd3(data, config);
chart1.createBubbleChart();
const chart2 = new acd3(data, config);
chart2.createBubbleScatterChart();
