logfile navigator ( https://news.ycombinator.com/item?id=33989493 https://news.ycombinator.com/item?id=33989493 ) does a nice cli/text visual presentation. Can be used to filter out 'noise' before piping output to be reformated / computing additional "stats" / generating appropriate info usable by next command in pipeline via gawk before passing on to other graphing packages such as nroff's graph, gnuplot, ggplot2, pdf/ps template, latex, etc.
