Color of the graph was based on the modularity class to highlight the clusters.

Node size was based on betweenness centrality using a range of 10 min – 40 max which identified the significant hubs.

Secondly, I ran data analysis using the statistics provided by Gephi with the following outcomes:įigure 2 shows that most of the airports had only little degrees, and there were only few airports enjoyed comparatively large number of connections with others. Data Visualization generated using Force Atlas layout Choosing Visualization Layout: Force Atlasįirst of all, I chose Force Atlas, one of the force-directed algorithms, to generate the graph (Figure 1) with repulsion strength 2000 for expansion so as to prevent overlap. After the adjustments, I imported the new dataset I made into Gephi and ready for the next step.ġ. Therefore, I exported the table and used OpenRefine to organize it, separating the data into three independent columns. After I opened the file, I checked the dataset and that the edge table had valid source, target, type, and weight attributes, yet in the node table, the label, longitude, and latitude of the airport were all in one column that couldn’t work for visualization in Gephi. A Network Map of the World’s Air Traffic Connections Methods & Processįrom Gephi Wiki, I grabbed the dataset ( Infrastructure Networks - Airlines) which was in GraphML format that could be opened directly in Gephi to do network analysis and visualization. However, I wonder if it’s better to show the visualization only in geographical layout since the clusters were mainly corresponding to the regions.

Overall, I think this layout delivered the information clear enough with the color use, node size difference, and the categorical labels.

It chose to present in the force-directed layout that allows readers to see the relationships beyond geographical location but also shows another visualization layout in line with the geographical map on the top right.

This data visualization of World’s Air Traffic Network looked at the quantity and connections of worldwide air transport, using nodes as airports, the size of the nodes indicating the number of routes, and color to show continents. Which airports are the hubs that serve as the important connections for the others?.What’s the community structure of America’s airspace system?.By using the dataset Infrastructure Networks - Airlines from Gephi Wiki, I was interested to find out: Since there were plenty of airlines and airports co-operating in the network, I was curious about the connections and relationships between them. According to Federal Aviation Administration, there were 44,000 flights every day and up to 16,100,000 flights handled by them yearly. I was fascinated by the vivid illustration and surprised at the vastness and the complexity of America’s airspace system. Air Traffic created by Aaron Koblin presented the bustle transportation network up in the sky. A 1961 photograph shows only cuts and soil ramparts where the future SR 16 would be built.U.S. Widely spaced vehicles drive on gleaming concrete through the South 56th Street cloverleaf. Photographs from I-5’s early days look almost too good to be true. It would also aid commerce - a crucial factor in a port city. The system was intended to improve safety and reduce congestion on city streets and highways.

The plan, dating from the 1940s, was to build a nationwide system of multi-lane roads free of intersections - the modern freeway. Richards Studio Northwest Room, Tacoma Public LibraryĬonstruction of what would become a nonstop roadway from the Mexican to Canadian borders began shortly after President Dwight Eisenhower’s signing of the Federal Aid Highway Act of 1956. Part of downtown Tacoma and the tideflats can be seen at the top edge of the picture. The large area of cleared land at the bottom of the photograph is the future home of the Tacoma Mall. The building to the left of the cloverleaf is Langendorf Bakery, 2202 S. The excavation work has begun, and the 38th Street bridge over I-5 is complete. 17, 1960 shows the I-5 interchange at South 38th Street.
