Forest Plot with Heterogeneity Bands
Note: this project was built as a submission for Wonderful Wednesdays.
Heterogeneity bands augment classic forest plots to provide a better visualization of heterogeneity between studies.
- There is a band for each study, and its width is equal to that of the corresponding confidence interval.
- All bands are transparent and superimposed over each other to visualize the overlap between intervals. Overlap between bands produces darker areas.
- A visual indication of homogeneity is when darker areas take larger proportions of the total width.

Technologies
The visualization is built with D3.js and rendered in a Shiny app using R2D3.
