Data Visualization Journal

    I chose a bar graph because it clearly shows how each category ranks from highest to lowest. This visualization makes it easy to see which categories lead and which fall behind, allowing quick comparisons across the entire dataset.  The story the visualization tells is straightforward: viewers can immediately identify the top-performing category, see how the rest compare, and spot any major gaps between them. As for the part-to-whole design framework , its strength lies in showing how individual parts contribute to the total, helping provide context for the whole picture. However, its limitation is that when there are many small categories, it can become difficult to see differences between them, especially in pie or donut charts.

  Module #4 Assignment: Time Series Visualization with Tableau Public I chose Year, Primary USA City, Vehicle Revenue Miles, Vehicle Revenue Hours, Ridership, and Collisions with Motor Vehicle because they highlight both operational performance and safety outcomes over time. These variables together reveal how miles and hours relate to ridership trends and potential safety concerns. I mainly looked into if the miles driven increases the collisions and what year and city most accidents happen. The information was a bit all over the place but it did show a lot of accidents happen in NY. <!-- wp:embed {"url":"https://public.tableau.com/views/Module4assignment_17585375775670/Sheet2?:language=en-US\u0026amp;:sid=\u0026amp;:redirect=auth\u0026amp;:display_count=n\u0026amp;:origin=viz_share_link","type":"rich","providerNameSlug":"embed"} --> <figure class="wp-block-embed is-type-rich is-provider-embed wp-block-embed-emb...

 I had trouble figuring out how to use adobe illustrator. It wasn't that the site was difficult to read it that my file from last week wouldn't work properly when trying to upload. I ended up having to make a map with the same data and using that. Last week's map will look different then this weeks because of that. I chose to go with pretty standard colors nothing too bold just clear to understand. By having red and greens I think it makes it bright enough for people to see. To enhance the map further, I added vector icons to show where the most libraries are and a few simple lines to show boundaries. These additions provided helpful reference points. Gestalt principles helped when deciding where to put labels to help people understand more, Overall the design could use some work, but I feel like it's clear with colors and labels.  https://assets.adobe.com/id/urn:aaid:sc:US:7445a4bf-3c0f-403c-bde1-f8fa220dcefe?view=published

  My data source was found on Google Dataset Search and was then exported into an excel file. I had so much trouble with Tableau Public; I think it's one of my least favorite tools that I've used in my classes so far. I couldn't get the colors or sizing to work for the longest time; I finally was able to have each library have its own color. I tried to not have the sizing be too small, but it kept glitching and making the screen really tiny. I don't know if it's just because it's the free public tool, but I feel like labeling the different functions better would make it easier on newer people. I was also watching videos on how to do it, and I feel like different people had functions and abilities to change things that I didn't have. I think when a lot of libraries are in the same area it makes the system confused and makes it look all jumbled up, I don't know if that was everyone or just me. There was a pattern in the zip codes and proximity so maybe tha...
