csv2svg

Build a SVG graph from a csv document.

Installation

You must have Rust installed. Do

cargo install csv2svg

Usage

Viewing the SVG graph in a browser

If you don't pipe the output of csv2svg, the graph is automatically displayed in your browser. For increasing readability the graph reacts to mouse hovering.

app_whose_output_is_csv | csv2svg

csv2svg < some/file.csv

Making a file from the SVG graph

app_whose_output_is_csv | csv2svg > some/file.svg

csv2svg < some/file.csv > some/file.svg

Example

The examples/irregular-times.csv files contains this:

time,something,another thing,a third one,whatever,bof

It may be used with no configuration:

csv2svg < examples/irregular-times.csv

which produces this:
