Textual visualization
Displays that use text refer to packages that do not need a graphics engine (such as QT). The graphics are generated in one of two ways:
- Using normal printable characters, either ASCII and/or Unicode
- By writing textual markup, normally based on LaTeX, though via Postscript or even directly to a PDF is possible
We learned how to implement the first of these methods previously, but it will be useful to briefly mention it again here.
Simple inline displays
When we provided an overview of Julia in Chapter 1, we briefly saw that it is possible to create some quite sophisticated text graphics (that is, using printable characters) using the UnicodePlots
package. It is the successor of early packages such as ASCIIPlots and TextPlots and provides a wider variety of available graphic types to display.
We saw examples of a line plot and a histogram in Chapter 1. As a quick refresher, I’ll create a horizontal bar plot of the populations...
