Tableau: Book6 | Tableau Public


Tableau is nice. Earlier today, I took some time to clean the data. I grouped the dataset by year and summed the riders, vehicle collisions, and person collisions. This left me with a small data frame that tableau would be able to handle. At some point of inserting the above image, it clicked for me that tableau does the necessary data cleaning for you. Earlier, I was concerned that tableau would not be able to handle the dataset without some simplification. I was wrong, and without further cleaning of the data the following line chart took about 45 seconds to make. Thats pretty cool.

Network Analysis

Daniel Tafmizi Dr. Friedman November 17, 2024 Lis 4317 Module 12 Github:  daniel.R/Work.R/LIS4370Rprog/networkAnalysis.R at main · DanielDataGit/daniel.R I enjoyed working on this network analysis. I was hoping to incorporate a similar element into my text mining final project, so this lesson acts a precursor to that. I used some reddit data that I retrieved from their API. I started by preprocessing the data, then I tokenized it, finally I found co-occurrences. The ggnet2 streamlines well with igraph. This allowed me to create a network analysis of co-occurrences from the reddit text. Further research will be done to add more elements to the graph. I would like to color in the nodes based on their connection to the keywords, "Kamala":Blue and "Trump":Red. Words related to both will be colored purple.

Multivariate analysis

Daniel Tafmizi Dr. Friedman October 29, 2024 Lis 4317 Module 9 Github:  daniel.R/Work.R/LIS4370Rprog/stockexchange.R at main · DanielDataGit/daniel.R This week I worked on preparing for the final project. I want to create something similar to the Gapminder life-expectancy vs gdp per capita graph. I would like to create one that shows the market cap of major stock exchanges vs their yty % change, over time. In beginning this endeavor, I searched and have found a good resource for the data at world-exchanges.org. I used their "statistics portal" to get some data for a multivariable visualization.  The graph shows the market cap and YTY change in 2023 for a few of the largest stock exchanges. I used colors to group by region. I used size to show how many companies make up the stock exchange.  Alignment: This can be added by maintaining a certain style amongst elements of a similar connection. Repetition: This can be added by using a consistent style to tie together separate ...

Daniel Tafmizi Dr. Friedman December 3, 2024 Lis 4317 Stock Exchange Analysis Github:  daniel.R/Work.R/LIS4370Rprog/4317FinalProjectCode.R at main · DanielDataGit/daniel.R Kaggle:  Global Stock Exchanges (Cap = 1 trillion+) 04-23      A stock exchange, securities exchange, or bourse is  an exchange where stockbrokers and traders can buy and sell securities, such as shares of stock, bonds and other financial instruments.   -   Stock exchange - Wikipedia     I was interested in seeing how global stock exchanges compare. I decided to construct my comparison by visualizing the market capitalization and performance of exchanges worth north of One trillion USD. Market capitalization is the sum of all securities in the exchange. This allows us to inspect the economic significance of the exchange. Performance is seen through the overall returns in the exchange. This allows us to inspect the quality and growth potential of the exchange. Through m...
