-==
-
-c3 is a D3-based reusable chart library that enables deeper integration of charts into web applications.
-
-Follow the link for more information: [http://c3js.org](http://c3js.org/)
-
-## Tutorial and Examples
-
-+ [Getting Started](http://c3js.org/gettingstarted.html)
-+ [Examples](http://c3js.org/examples.html)
-
-Additional samples can be found in this repository:
-+ [https://github.com/masayuki0812/c3/tree/master/htdocs/samples](https://github.com/masayuki0812/c3/tree/master/htdocs/samples)
-
-You can run these samples as:
-```
-$ cd c3/htdocs
-$ python -m SimpleHTTPServer 8080
-```
-
-## Google Group
-For general C3.js-related discussion, please visit our [Google Group at https://groups.google.com/forum/#!forum/c3js](https://groups.google.com/forum/#!forum/c3js).
-
-## Using the issue queue
-The [issue queue](https://github.com/masayuki0812/c3/issues) is to be used for reporting defects and problems with C3.js, in addition to feature requests and ideas. It is **not** a catch-all support forum. **For general support enquiries, please use the [Google Group](https://groups.google.com/forum/#!forum/c3js) at https://groups.google.com/forum/#!forum/c3js.** All questions involving the interplay between C3.js and any other library (such as AngularJS) should be posted there first!
-
-Before reporting an issue, please do the following:
-1. [Search for existing issues](https://github.com/masayuki0812/c3/issues) to ensure you're not posting a duplicate.
-
-1.  [Search the Google Group](https://groups.google.com/forum/#!forum/c3js) to ensure it hasn't been addressed there already.
-
-1. Create a JSFiddle or Plunkr highlighting the issue. Please don't include any unnecessary dependencies so we can isolate that the issue is in fact with C3. *Please be advised that custom CSS can modify C3.js output!*
-
-1. When posting the issue, please use a descriptive title and include the version of C3 (or, if cloning from Git, the commit hash — C3 is under active development and the master branch contains the latest dev commits!), along with any platform/browser/OS information that may be relevant.
-
-## Pull requests
-Pull requests are welcome, though please post an issue first to see whether such a change is desirable.
-If you choose to submit a pull request, please do not bump the version number unless asked to, and please include test cases for any new features!
-
-## Playground
-Please fork this fiddle:
-+ [http://jsfiddle.net/masayuki0812/7kYJu/](http://jsfiddle.net/masayuki0812/7kYJu/)

-## Dependency
-+ [D3.js](https://github.com/mbostock/d3) `<=3.5.0`

-        <h1>C3 DataSet Reduction by Zoom Level</h1>
-        <h2>Hackathon May 2014</h2>
-        <h4>By Dan-el Khen</h4>
-        <p>Rendering graphs in the browser has many advantages, the downside is that takes a long time to render when having large datasets. </p>
-        <p>This feature allows you reduces the dataset according to your current zoom level. 
-        It allows the developer to implement the reduction algorithm in a simple function that accepts an array of values, and returns a reduced single value.
-        The default reducer will take the first item, but avg/sum/first/last or any other algorithm is simple to implement.
-        </p>
-        <h3>Example</h3>
-        <p>
-            In the following example, we'll render 10K data points, each time we'll reduce those to about 100 items (depending on available size on your screen),
-            when zooming in, the resolution of the data will be better and more accurate. This would help in showing the big picture, even when the amount of data is bigger than the numbers of pixels on the screen.
-        </p>
-        <p>Click on the buttons or scroll with your mouse wheel inside the graph to zoom and/or pan.</p>
-        <pre id="status"></pre>
-        <div>
-            <button onclick="chart.zoom2.zoomIn()">zoomIn</button>
-            <button onclick="chart.zoom2.zoomOut()">zoomOut</button>
-            <button onclick="chart.zoom2.panLeft()">panLeft</button>
