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.
