<h1>Data visualization</h1>

<p>Just a collection of python scripts for visualizing data.</p>

<h1>Barycentric legend</h1>

<p>Given a pixel density and number of rows the script creates a triangular RGB legend based off
barycentric coordinates, useful when mapping trivariate data where variables always add to 1,
like <a href="https://en.wikipedia.org/wiki/Soil_texture">soil texture</a>.</p>

<h2>Script:</h2>

<pre><code>barycentric_triangle_legend.py
</code></pre>

<h2>Requirements:</h2>

<pre><code>- numpy
- pycairo
</code></pre>

<p>10 Rows          | 25 Rows  | 50 rows
