Create Fallback HTML Content — create_fallback

Creates HTML content with the fallback image, styled to fit in iframes. The image's alt text, which is what a screen reader says of it, names the chart by its title when it is given one, and says why it is an image.

Usage

create_fallback_html(
  plot = NULL,
  shiny = FALSE,
  format = get_fallback_format(),
  width = 7,
  height = 5,
  title = NULL,
  reason = c("unsupported", "failed")
)

Arguments

plot: A ggplot2 or trellis object, or NULL for Base R plots
shiny: If TRUE, returns just the image tag for Shiny/knitr use
format: Image format. Defaults to the maidr.fallback_format option, which maidr_set_fallback() sets.
width: Image width in inches
height: Image height in inches
title: The chart's title, or NULL; the alt text then calls it "Plot"
reason: Why the chart is an image: "unsupported", it holds elements maidr cannot read, or "failed", it could not be made interactive (build_interactive_svg())

Value

HTML content string or htmltools object
