A QTL is a *quantitative trait locus*: a genetic locus that contributes to variation in a quantitative trait. The goal of [R/qtlcharts](https://kbroman.org/qtlcharts/) is to provide interactive data visualizations for QTL analyses, and to make these visualizations available from R. It is a companion to the [R/qtl](https://rqtl.org) package.
