        Datashader is a data rasterization pipeline for automating the process of
        creating meaningful representations of large amounts of data. Datashader
        breaks the creation of images of data into 3 main steps:
        
        1. Projection
        
           Each record is projected into zero or more bins of a nominal plotting grid
           shape, based on a specified glyph.
        
        2. Aggregation
        
           Reductions are computed for each bin, compressing the potentially large
           dataset into a much smaller *aggregate* array.
        
        3. Transformation
        
           These aggregates are then further processed, eventually creating an image.
        
        Using this very general pipeline, many interesting data visualizations can be
        created in a performant and scalable way. Datashader contains tools for easily
        creating these pipelines in a composable manner, using only a few lines of code.
        Datashader can be used on its own, but it is also designed to work as
        a pre-processing stage in a plotting library, allowing that library
        to work with much larger datasets than it would otherwise.
        
        
        ## Installation
        
        The best way to get started with Datashader is install it together
        with our extensive set of examples, following the instructions in the
        [examples README](/examples/README.md).
        
        If all you need is datashader itself, without any of the files used in
        the examples, you can install it from the `bokeh` channel using the using the
        [`conda` package manager](https://conda.io/docs/install/quick.html):
        
        ```bash
        conda install -c bokeh datashader
        ```
        
        If you want to get the very latest unreleased changes to datashader
        (e.g. to edit the source code yourself), first install using conda 
        as above to ensure the dependencies are installed, and you can
        then tell Python to use a git clone instead:
        
        ```bash
        conda remove --force datashader
        git clone https://github.com/bokeh/datashader.git
        cd datashader
        pip install -e .
        ```
        
        Datashader is not currently available on PyPI, to avoid broken or
        low-performance installations that come from not keeping track of
        C/C++ binary dependencies such as LLVM (required by Numba).
        
        To run the test suite, first install pytest (e.g. ``conda install
        pytest``), then run ``py.test datashader`` in your datashader source
        directory.
        
        ## Learning more
        
        After working through the examples, you can find additional resources linked
        from the [datashader documentation](http://datashader.org),
        including API documentation and papers and talks about the approach.
