Data Display Framework

Data Display
Data representation in general, not just visualizations

Framework
Not another library, but a framework to bind them all

Current Situation

• Countless JavaScript visualization libraries available
• Each works differently
• Some are specialized for one task
• Some are tied to a very specific envirionment
• Nearly all of them require programming knowledge

plastic.js Specs (1/2)

• Open Source: github.com/Fannon/plastic.js
• Platform neutral: Pure HTML5
• Easy to use: No programming skills required
• Modular: Loosely coupled architecture
• Extensible: Data Modules, Query Modules, Display Modules

plastic.js Specs (2/2)

• Framework: Providing a platform for existing libraries
• Dependency Management: "Smart" lazy loading
• Schemas: Uses schemas, falls back to duck-typing
• Async: Runs asyncronally and possibly multithreaded

Include plastic.js in a HTML page

<link rel="stylesheet" href="lib/plasticjs/plastic.css">
<script src="lib/plasticjs/plastic.js"></script>

plastic.js Usage

• Can be put into any HTML page through an embed code
• Lightweight wrapper extensions for common CMS
• Example: MediaWiki Wrapper Extension

Simple Table from JSON

<plastic style="height: 400px; width: 800px;">

    <div class="plastic-data"
         data-url="data/simple-default.json"
         data-format="simple-default">
    </div>

    <div class="plastic-display" data-module="simple-table"></div>

</plastic>

Simple Table from JSON

Simple Bars from SPARQL Endpoint

<div class="plastic-js" style="height: 400px">
    <script class="plastic-query" type="application/sparql-query" data-query-url="http://dbpedia.org/sparql">
        PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
        PREFIX type: <http://dbpedia.org/class/yago/>
        PREFIX prop: <http://dbpedia.org/property/>

        SELECT ?country_name ?population
        WHERE {
            ?country a type:LandlockedCountries .
            ?country rdfs:label ?country_name .
            ?country prop:populationEstimate ?population .

            FILTER (?population > 12000000 && langMatches(lang(?country_name), "en")) .
        }
        ORDER BY DESC(?population)
    </script>
    <script class="plastic-display" data-module="discrete-bar-chart" type="application/json">
        {
            "tooltips": true,
            "showValues": true
        }
    </script>
</div>

Module Sequence Flow

Internal datastructure

• 2.5D Table: Table where each cell is an array of values of the same datatype
• Not the most flexible dataformat, but a good compromise of flexibility and easy usage.

JSON Schema at heart

• Lightweight alternative to XMLSchema
• Describes the data to the display modules
• Validating incoming data and options
• Auto-generate parts of the user documentation

In early development

• Working Architecture
• Several data formats supported
• Able to query SPARQL Endpoints and semantic wikis
• A few simple display modules (tables, bars, pies)
• Wrapper Extension for MediaWiki

Roadmap

• Automatically reflect and apply changes from the embed code
• Provide more modules
• Documentation++

Problems to solve

• How to deal with tree and graph data?
• Some Display Modules make only sense with a specific kind of data.
• Manage Module Requirements and Features.
• Asynchronous exception handling
