Phase 1 Project Progress

For Phase 1, I used NYC Open Data for my data set source, because I am interested in data related to the place we're living in. So I decided to explore a little about the data source and see what data set I would use. To be honest, I think trying to find the right data set you want is one of the difficult part of the process. I spent a lot of time searching for the data set I'm interested in and also good for working. I picked two data sets to be my practice on using Tableau, one is "NYC 1995 Street Tree Census", and another one is "Water Consumption in NYC". I'm not sure they will be my phase 1 final data set or not, but trying to visualize those data set in Tableau is fun and interesting. Seeing those numbers turn into diagrams, bars and lines makes me feel accomplished. 

1. Data Set: 1995 Street Tree Census

Citywide street tree data from the 1995 Street Tree Census, conducted by volunteers organized by NYC Parks & Recreation. Trees were inventoried by address, and were collected from 1995-1996. Data collected includes tree species, diameter, condition.

Tableau 

Tableau has a very large customer base across many industries due to its simplicity of use and ability to produce interactive visualizations far beyond those provided by general BI solutions. It is particularly well suited to handling the huge and very fast-changing datasets which are used in Big Data operations, including artificial intelligence and machine learning applications, thanks to integration with a large number of advanced database solutions including Hadoop, Amazon AWS, My SQL, SAP and Teradata. Extensive research and testing has gone into enabling Tableau to create graphics and visualizations as efficiently as possible, and to make them easy for people to understand.

Datasets

NYC Open Data

NYC Open Data provides an opportunity to engage New Yorkers in the information that is produced and used by City government. The Mayor’s Office of Data Analytics (MODA) and the Department of Information Technology and Telecommunications (DoITT) partner to form the Open Data team. It's a place we can find out where can we find public Wi-Fi in the neighborhood, what kind of tree is in front of your office..and more.
