NVD3 is an attempt to build re-usable charts and chart components
for d3.js without taking away the power that d3.js offers you.

Python-NVD3 makes your life easy! You write Python and the library
renders JavaScript for you!
These graphs can be part of your web application:

Want to try it yourself? Install python-nvd3, enter your python shell and try this quick demo::

>>> from nvd3 import pieChart
>>> type = 'pieChart'
>>> chart = pieChart(name=type, color_category='category20c', height=450, width=450)
>>> xdata = ["Orange", "Banana", "Pear", "Kiwi", "Apple", "Strawberry", "Pineapple"]
>>> ydata = [3, 4, 0, 1, 5, 7, 3]
>>> extra_serie = {"tooltip": {"y_start": "", "y_end": " cal"}}
>>> chart.add_serie(y=ydata, x=xdata, extra=extra_serie)
>>> chart.buildcontent()
>>> print chart.htmlcontent


This will output the following HTML to render a live chart. The HTML could be
stored into a HTML file, used in a Web application, or even used via Ipython Notebook::

<div id="pieChart"><svg style="width:450px;height:450px;"></svg></div>
<script>
data_pieChart=[{"values": [{"value": 3, "label": "Orange"},
{"value": 4, "label": "Banana"},
{"value": 0, "label": "Pear"},
{"value": 1, "label": "Kiwi"},
{"value": 5, "label": "Apple"},
{"value": 7, "label": "Strawberry"},
{"value": 3, "label": "Pineapple"}], "key": "Serie 1"}];

nv.addGraph(function() {
var chart = nv.models.pieChart();
chart.margin({top: 30, right: 60, bottom: 20, left: 60});
var datum = data_pieChart[0].values;
chart.tooltipContent(function(key, y, e, graph) {
var x = String(key);
var y = String(y) + ' cal';
tooltip_str = '<center><b>'+x+'</b></center>' + y;
return tooltip_str;
});
chart.showLegend(true);
chart.showLabels(true);
chart.donut(false);
chart
.x(function(d) { return d.label })
.y(function(d) { return d.value });
chart.width(450);
chart.height(450);
d3.select('#pieChart svg')
.datum(datum)
.transition().duration(500)
.attr('width', 450)
.attr('height', 450)
.call(chart);
});
</script>


Documentation
-------------

Check out the documentation on `Read the Docs`_ for some live Chart examples!

.. _Read the Docs: http://python-nvd3.readthedocs.org

Installation
------------

Install, upgrade and uninstall python-nvd3 with these commands::

$ pip install python-nvd3
$ pip install --upgrade python-nvd3
$ pip uninstall python-nvd3


Dependecies
-----------

D3 and NvD3 can be installed through bower (which itself can be installed through npm).
See http://bower.io/ and https://npmjs.org for further information.
To install bower globally execute::

$ npm install -g bower

Note : you might prefer to save your npm dependencies locally in a ``package.json`` file.

Then in the directory where you will use python-nvd3, just execute the following commands::

$ bower install d3#3.3.8
$ bower install nvd3#1.1.12-beta

This will create a directory "bower_components" where d3 & nvd3 will be saved.

Note : you might prefer to save your bower dependencies locally in a ``bower.json`` file.
You can also configure the directory where your bower dependencies will be
saved adding a ``.bowerrc`` file in your project root directory.


Django Wrapper
--------------

There is also a django wrapper for nvd3 available:
https://github.com/areski/django-nvd3


IPython Notebooks
-----------------

Python-NVD3 works nicely within IPython Notebooks (thanks to @jdavidheiser)

See the examples directory for an Ipython notebook with python-nvd3.
