CSVisFrame

This is the source code of CSVisFrame: A Framework for Interactive Visualizations of Abstract Concepts in Computer Science

Online Page

The demo page will come online as soon as possible.

Getting Started

Getting the source

git clone [email protected]:Jisuanke/CSVisFrame.git

This repo include two modules, Component and Visualization.

For Component

Build Component

npm install
npm run build

Usage

If you are using browserify to bundle your modules, use aliasify to redirect require('components') to ../Component/dist/index.min.js; for rollup.js users, you can use rollup-plugin-alias for the same effect.

API

All components live in the top module namespace. For example, to create a new vertex, you can write

# Remember to set up the alias
Components = require 'components'

# Let's first set up Components
Components.config
  parentNode: document.getElementById '#svg'
  colors:
    # For example, if we want to override the default color setting
    # for flagged elements:
    flagged: '#DE3E1E'

# We set up a Collection (group) to store all our vertices.
{ Collection, Vertex } = Components
vertices = new Collection 'vertices'

# and then add a new element:
vertices[0] = new Vertex
  id: 1
  fill: '#ABABAB'
  content: 'A'

# Finally, we draw the vertex within a duration of 750ms.
# It should appear in the page now.
vertices.draw 750

For Visualization

Build Visualization

# Install CoffeeScript and bower globally
npm install -g coffee-script
npm install -g bower

# Install dependencies and build demo page
npm install
gulp

# Build CSVisFrame for development (for use with modern browsers)
cake build

# Build CSVisFrame for production (minified and converted to ES5)
cake production

# Update the version number (only used when production)
cake bump

The builder mentioned above automatically produces the following files:

1. /lib/Algorithm/index.js

API

CSVisFrame = require 'csvisframe'

# Create a CodeMirror instance
codemirror = CodeMirror.fromTextArea ...

CSVisFrame.config

  # CodeMirror instance for pseudocodes
  codemirror: codemirror

  # Specify the time taken to finish transition to one state
  speed: 1200

  # Containers are passed straight to jQuery, so feel
  # free to pass anything that jQuery accepts.
  # N.B. Anything inside these nodes *will* be removed.

  containers:
    # Algorithm Demonstration
    SVG: '#viz'

    # Instruction
    guide: '#guide'

    # Progress Bar Slider
    # or with empty div
    progressBar: '#progress-bar'

    # Media Player Control
    player: '#player'

# Now we have finished configuring CSVisFrame. Let's initialize
# an algorithm demo.

# `queue` starts with members 10, 11, 12
queue = new CSVisFrame.Queue [10, 11, 12]

# Let's push three more members
queue.enqueue [20, 21, 22]

# ... and dequeue two of them
queue.dequeue()
queue.dequeue()

# Now `queue` has generated a list of states (animation frames).
# We tell CSVisFrame that we will play this specific list of states by
player = CSVisFrame.player
player.mount queue

# At this point, the user can control the animation by clicking
# play, pause, forward, backward, stop and dragging the slider.
# If you need to manually control the animation status. You can
player.play()
player.pause()
player.stop()
player.forceNext()      # Go to next step
player.forcePrevious()  # Go to previous step
