Provides text and label geoms for 'ggplot2' that help to avoid overlapping text labels. Labels repel away from each other and away from the data points.
ggrepel provides geoms for ggplot2 to repel overlapping text labels:
Text labels repel away from each other, away from data points, and away from edges of the plotting area.

feature labeling problem. The goal is to position the largest number of point labels such that they do not intersect each other or their points. First we present an algorithm using a greedy algorithm with limited lookahead. We then present an algorithm that iteratively regroups labels, calling the first algorithm on each group, thereby identifying a close to optimal labeling order. The presented algorithm is being used in a commercial product to label charts, and our evaluation shows that it produces results far superior to those of other labeling algorithms.
This might be a good start for a revision of ggrepel.
A small library for automatically adjusting text position in matplotlib plots to minimize overlaps.
Ilya Flyamer's Python library that extends matplotlib.
An extensible framework for automatically placing direct labels onto multicolor 'lattice' or 'ggplot2' plots. Label positions are described using Positioning Methods which can be re-used across several different plots. There are heuristics for examining "trellis" and "ggplot" objects and inferring an appropriate Positioning Method.
Pretty word clouds.
wordcloud package implements a spiraling algorithm to prevent text
labels from overlapping each other.
Force field simulation of interaction of set of points. Very useful for placing text labels on graphs, such as scatterplots.
I found that functions in the
FField package were not ideal for repelling
overlapping rectangles, so I wrote my own.

CHANGES (thanks to @AliciaSchep)
Add code to avoid intersecting line segments. See issue 34.
Fix intersection between lines and rectangles, to reproduce the same aesthetically pleasant behavior as in version 0.6.5.
This is an improvement on the sloppy implementation introduced in 0.6.8. See commit 28633d for more information.

repel_boxes.cpp. Dampen forces to tune how the labels move. The result looks better, at least for the examples in the vignette.

geom_label(). Backwards incompatible with 0.5.1.
segment.color as an option for
repel_boxes.cpp. Do not weight repulsion force by ratios of bounding
box heights and widths. This seems to perform better, especially after
rotating text labels.
point.paddingso that users can configure how far labels are pushed away from data points.
Optimize C++ code for a 2.5X speed improvment.
Delete unnecessary .Rd files.
geom_label_repel(). Now there is no gap between the end of the segment and the label border.
spring_force()so that it never returns NaN.
nudge_yto better control positioning of labels.
arrow parameter to allow plotting arrows that point to the labeled data
points rather than plain line segments.
Always draw segments, even if the labeled point is very close to the label.
point.padding so that horizontal and vertical padding is calculated
Tweak forces to improve layout near borders and in crowded areas.
Add new parameter
point.padding to add padding around the labeled points.
The line segment will stop before reaching the coordinates of the point. The
text labels are also now padded from the line segment to improve legibility.
Add volcano plot to the vignette usage examples.
Add Travis continuous integration to test against R-devel, R-release, and R-oldrel.
Dampen repulsion force to slightly improve algorithm efficiency.
Remove unused imports:
Update NAMESPACE with new version of roxygen.
Use spring force to attract each label to its own point.
Change default maximum iterations from 10,000 to 2000.
