This post will examine the Heber Valley Railroad, a small town
tourist attraction using event gravitational pull. Using the information from part 1 the two factors associated with the events gravity, the number of participants, and the distance they traveled. The number of participants can be shown using bar charts, histograms, and summary tables. The distance traveled can be displayed using bar charts, histograms, summary charts, and most important great circle maps. Below are some of the charts I created when doing the analysis.

The first two are bar charts show where the majority of train riders are coming from. From the graphs Salt Lake City Utah is number one, followed by Ogden, then it goes down hill from there very quickly. The purpose of these first graphs is to show how many people are coming to the event and where.

Where the first set of graphs show the cities, the histograms show where people are coming from in terms of distance. The first histogram shows all the data, the next two are zoomed in to show the majority of people travel less than 100 miles (as the crow flies) to get to the train. While the majority of people who ride the train do so within 100 miles, there are many who travel many miles. But it should be noted, there are only 1-3 customers per line. The map looks really good, but the majority of those traveling long distances, are much fewer.

While the map shows a number of people coming from various locations, there are only 1-3 people per line, nothing to really spend any marketing funds to. The map does show how far people do come.

The next two maps show that within Utah the majority of people riding the train come from Salt Lake, Ogden, and the Wasatch Front area.
