City of Atlanta

The City of Atlanta data visualization suite includes 400 variables all mapped to City of Atlanta neighborhoods, neighborhood planning units (NPUs), and City Council districts’ boundaries. The data includes several City-specific variables such as code enforcement, 911 calls and the results of the recently-conducted windshield survey of housing conditions, as well as hundreds of Census variables like income, poverty, health insurance coverage and disability. When we say “neighborhoods”, we actually mean “Neighborhood Statistical Areas,” which in some cases combine some of Atlanta’s smaller neighborhoods into one.

The tools we built include an interactive map, which allows for a deep-dive analysis of all 400 variables, and a dashboard, which is an easy-to-use tool that provides quick comparisons of every neighborhood, neighborhood planning unit, and City Council district to the city as a whole.

Data Dashboard

The Data Dashboard enables the use to find and map key indicators for every neighborhood, NPU, and City Council district within the City of Atlanta.  The tool includes both an interactive map and report interface. The map interface enables the comparison between geographic areas within the city based on a drop-down selection of numerous indicators across and an array of categories. The report portion of the tool enables a closer look at a chosen geographic area (selected using the map) and can be tailored to the user’s specific topic of interest with pre-formatted report types.

  1.  Choose Geography Type.
  2.  Select data Category and Indicator to change Map View.
  3.  Explore MapView by hovering cursor over a neighborhood.
  4.  Click on a neighborhood to show its information in the Report View.
  5.  Select Report Type to change indicators listed in the Report View.

Interactive Mapping

The Interactive Maps below displays 400 indicators for City of Atlanta neighborhoods, neighborhood planning units (NPU), and City Council districts. Simply click on the “View Instructions” link to get a basic overview on using the map.

  • Map: To change the variable being mapped, click on the α (alpha symbol) next to the “Color Legend” and select a category from the left side of the table and a variable from the right side of the table. By hovering over the map, you can open pop-up windows with details about the variable being mapped. In the map you can use the zoom tools, select the pan tool (hand symbol) to move around, or use the square selection tool (arrow over square) to draw a box and zoom into that area.

  • Scatterplot: If there is not a scatter plot in the window, select the tools menu at the top of the window and click on scatterplot. To change the variables on the X (horizontal) and Y (vertical) axes, simply click on the axis title and select different variables for each axis. If the regression line is not showing, you can click the gear icon in the scatterplot window, select the advanced tab, and check the box to enable trendline. The regression line shows “neatness” of fit- the relationship between the two variables. Any point that is a significant distance from the line is an “outlier,” meaning that the expected relationship (the line) does not hold.
  • Data Table: At the very bottom of the map window, there is a small white box. If you click it, it will expand and reveal a data table. Click on the α (alpha symbol) next to “Advanced Table” in the upper-left corner, you can use the selector to add the data variables you want to the export. Once you are finished, you can click on the main file menu at the top and export the table as a .CSV file. The data displayed in the map is linked to both the data table and the scatterplot, meaning that if you select a feature on the map, data in the data table, or dots on the scatterplot, that same feature will be highlighted in all the windows.
  • Subsets: If you want to narrow down the number of features being mapped, you can click on “Subsets” on the main menu and click one of the existing subsets. Or, you can select your own features (from the map, table, or scatterplot), and select “Create subsets from selected records.” You’ll notice that both the legend and the scatter plot changed to reflect only the area that was selected.
