In this post, I provide access to a data visualizer for the Pennsylvania lottery using data I pull regularly from their RSS feed. This tool uses SQLite and some scripts to automatically pull data to this post which is then visualized using Chart.js. I created histograms of the most common drawn numbers for the drawings in which a particular number appears, and you can see that visualized below in the charts.

## Frequency of Numbers given that X is part of the drawing

This chart displays the relative frequencies of a value coming up given that X showed up in the results. Numbers are counted exactly once within a drawing, so if 000 came up it would count as exactly 1 count for 0,0. The results are then normalized using count divided by the row sum.

## Overall Frequency of Individual Numbers

So I just recently collected this data from the RSS feed, so it doesn't go back too far, but I plan on keeping it running for as long as I can collecting new data. So use this tool to explore the lottery data, as a histogram or in other formats.
