You run `clj` to get a Clojure REPL

Then you can for instance paste the following into the REPL

    (add-libs {'thi.ng/geom {:mvn/version "1.0.0-RC4"}})
    (use 'thi.ng.geom.viz.core)
    (use 'thi.ng.geom.svg.core)

    (->> {:x-axis (linear-axis
                {:domain [-10 310]
                    :range  [50 550]
                    :major  100
                    :minor  50
                    :pos    150})
        :y-axis (linear-axis
                {:domain  [0 4]
                    :range   [50 150]
                    :visible false})
        :data   [{:values  [[0 100] [10 90] [80 200] [250 300] [150 170] [110 120]
                            [210 280] [180 280] [160 240] [160 170]]
                    :attribs {:stroke-width "10px" :stroke-linecap "round" :stroke "#0af"}
                    :layout  svg-stacked-interval-plot}]}
        (svg-plot2d-cartesian)
        (svg {:width 600 :height 200})
        (serialize)
        symbol)

- the second and third line add the library to the REPL's default namespace

- the rest of the code makes an axis and plots some random values

- the output is then serialized and send out the REPL output

You should get a little SVG plot on the output

PS: Make sure you have version `1.12` by running with `clj --version`. If not, then (re)run the instructions here to get the latest version: https://clojure.org/guides/install_clojure
