 # Interactive eQTL plot
 #
-# In top figure, x-axis corresponds to marker location, y-axis is
-# genomic position of probes on a gene expression microarray Each
-# plotted point is an inferred eQTL with LOD > 10; opacity corresponds
-# to LOD score, though all LOD > 25 are made fully opaque.
+# adapted from https://github.com/kbroman/d3examples/tree/master/cistrans
 #
-# Hover over a point to see probe ID and LOD score; also highlighted
-# are any other eQTL for that probe.  Click on the point to see LOD
-# curves below.
-#
-# Hover over markers in LOD curve plot to view marker names; click on
-# a marker to see the phenotype-vs-genotype plot to right.  In
-# geno-vs-pheno plot, hover over average to view value, and hover over
-# points to view individual IDs.
