The text! function is just a convenience around the Title type in the same way as the title! function, so that end-users don’t need to reference ec.title directly (though, nothing prevents users modifying the EChart chart instance).
Two methods are provided. If you just want to append a piece of text to the EChart, you can use the method without specifying a series. If you want to modify a piece of text in place, specify its series (such as to change the font without changing the text or other features).

Add text to a chart
using ECharts, RDatasets
df = dataset("datasets", "mtcars")
sgrp = scatter(df, :MPG, :HP, :Cyl)
title!(sgrp, text = "Horsepower vs. Miles Per Gallon")
text!(sgrp, subtext = "Source: mtcars dataset from R", left = "0%", bottom = "0%")Modify text in place - Add HTML link
text!(sgrp, 2, sublink = "https://stat.ethz.ch/R-manual/R-devel/library/datasets/html/mtcars.html")
