Click me! Instructions on using Weave
Instructions for manipulating the map and the scatter plot:
The data displayedin the map is linked to both the data table and the scatterplot, meaning that if you select data in the data table or dots (which represent census tracts) in the scatterplot, the corresponding areas on the map will be highlighted.
Scatter plot: To change the variables on the X (horizontal) and Y (vertical) axes, simply click on the title and select different variables for each axis. Also notice the thin line - this is a regression line that shows "neatness" of fit. It shows 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 this Weave instance, there is a tiny box. If you click it, it will expand and reveal a data table. If you then click on the wrench in the upper-left corner, you can use the selector to add whatever data you want to the table. Once you are finished, export it as a .CSV file.
If you are interested in a small area, choose the "select" tool - underneath the zoom bar on the map - and draw a box around the area that you want to analyze in-depth. Then on the menu bar, click "Subsets", then "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.
