This page live-fetches the TSA checkpoint travel numbers (current year(s) versus prior year/same weekday)
web page, grabs the HTML text, turns it into a DOM, extracts the HTML <table> columns and turns them into an {arquero} table, then passes it on to {Plot}.
Each time you load/refresh the page, the live data will be retrieved. No more R, {ggplot2} & cron jobs for some basic, dynamic visualizations!
