Therefore, by using the internal grouping function from Tableau, I grouped them into four big categories and created another column for the new location types-indoor, outdoor, library, and subway station. For example, in the following picture, the data “indoor ap – community center – computer rm” includes too much minor details. WiFi location types and their connection typesīefore I started visualizing, I found the data “location type” contains some insignificant information that may not be useful or too trivial for people to know when searching a specific WiFi hotspot.WiFi connection types supported by providers.The number of WiFi hotspots in a region.Ultimately, I decided to use the five primary data-”provider”, “location”, “location types”, “connection types”, “number of records”, and “postcode” to form the four design directions: For example, I found the data “postcode” and “number of records” may help to advise the number of hotspots in a region I can use “location type” and “provider” to tell what the WiFi location type the provider supports. I first tried to find the data that have some degrees of relationship in between and may deliver useful information. Exploring deeply the dataset and deciding the design directions for the visualizations. By using Tableau Public, I intend to build a useful tool that people can search a specific WiFi hotspot and know its properties that may be helpful for them to plan to go. Even though public WiFi hotspots cannot guarantee the reliability and have some risks such as low security and low speed, they become more and more important in the modern society since the internet has become the basic amenities for the modern public.įor this project, based on the dataset- NYC WiFi Hotspot Locations from NYC Open Data, I aim to create an interactive visualization that can inform people of the exact locations of the WiFi hotspots in New York City, supported by analyses of the properties and configuration of the hotspots. The public can access the wireless connection by using a laptop or other suitable portable device, which is really beneficial that public like budget-tight students can gain tremendously from it. They usually created by a business for public use, often found at airports, libraries, train stations, etc. Public WiFi hotspots are physical locations where people can obtain Internet access. The project is to visualize the WiFi hotspots in New York City, which is the extension from my fourth lab project.
