(Beta Release) Visualization 2 - New Building Permits in San Francisco by Neighborhood and Year

Feedback

Feedback: "May be you can reduce the repeating color some how."
Response: In my d3 implemented visualization of the beta release I implemented a color scale encoded off the total number of permits to ensure there are not any duplicated colors. I also added interactivity to hover over each line and see a tooltip with the neigborhood name, the percentage of total permits and the total number of permits for that individual line.

Feedback: "Sizing for the second visualization can be worked on in order to clear the clutter. Maybe use grouping or interactivity to help with this."
Response: In my d3 implemented visualization of the beta release I added interactivity to hover over each line and see a tooltip with the neigborhood name, the percentage of total permits and the total number of permits for that individual line. I took this feedback into account when adding the interactivity to add clarity and ensure the visualization was useful to the overall narrative.

Feedback: "A bit too many colors."
Response: In my d3 implemented visualization of the beta release I implemented a color scale encoded off the total number of permits to ensure there are not any duplicated colors. I also added interactivity to hover over each line and see a tooltip with the neigborhood name, the percentage of total permits and the total number of permits for that individual line.

Feedback: "Data is a little too dense because of scales"
Response: In my d3 implemented visualization of the beta release I implemented the hovering and clicking interactivity to provide a solution for the high level of density so it can be explored better by hovering and clicking.

Positive Feedback: I understand that the overall trends between the years seem to reflect on all neighborhoods (spikes and drops).
Positive Feedback: I think it's good that you're planning on adding some interactive filtering to let the user look at the data in a less cluttered space.
Positive Feedback: Context is provided and easy to understand
Positive Feedback: There is a good amount of interactivity planned, I really like that when you click on the bar chart you will highlight the line corresponding to that neighborhood.
Positive Feedback: Another visualization for interactivity will be really good, also sorting and clicking on them sounds nice.

Goal

My goal for this visualization is to show the user the trend in new buildings permits for each neighborhood in San Francisco over the range from 1973 - 2019. Certain neighborhoods in San Francisco are known for high building development and this visualization provides further detail from visualization 1 and allows the user to see if this growth is consistent or if there are specific high and low years.

Planned Interactivity

Hover: The user will be able to hover over each line and as one moves along the line specific points for each year will show values in a tooltip.
Click/Highlight: The user will be able to click a line or a neighborhood in the legend to gray all lines except the clicked one. There will also be an option to click multiple lines/neighborhoods to perform easy comparisons.
Interactive with Visualization 1: The main idea with my project is that I will have this visualization, visualization 1, and a third map of SF. All three will be interactive and work together. Clicking a neighborhood on the bar chart will highlight the neighborhood in all three visualizations. A lot of the features are embedded in the interactivity.

Encoding

This is a line chart representing the number of new building permits in San Francisco for each neighborhood by year. The y-axis is encoded using the number of new building permits and the x-axis is encoded by year with the range of January 1973 - April 2019. Each line has a color that corresponds to the legend color for each neighborhood.

Data Processing

From the original dataset I performed filtering to retrieve the dataset appropriate for this visualization. The column titled "permit type" was filtered for "2" only, which is "new construction wood frame". The column titled "Neighborhoods - Analysis Boundaries" also filters out all blank values so we have neighborhood names for all new construction permits. The data is from Novermber 20, 1973 to April 10, 2019. I rolled up the count of permits of type "2" to receive the count for each year from 1973 through 2019.
