SVG Interactivity

kuva can embed browser interactivity directly into SVG output — no server, no external dependencies, no JavaScript CDN. Everything is self-contained in the .svg file.

Try it

The volcano plot below is fully interactive. Click inside it and try:

Type BRCA1 in the search box to find it instantly
Try TP53, MYC, KRAS, EGFR, or any gene name
Hover any point to see the gene name, fold change, and p-value
Click a point to pin it; Escape to clear
Click Up or Down in the legend to toggle those series

Generated with: kuva volcano data.tsv --name-col gene --x-col log2fc --y-col pvalue --legend --interactive --top-n 15 -o volcano.svg

Enabling it

Library:

#![allow(unused)]
fn main() {
let layout = Layout::auto_from_plots(&plots)
    .with_interactive();
}

CLI:

kuva scatter data.tsv --x x --y y --color-by group --legend --interactive -o plot.svg

The flag is accepted by every subcommand. Open the output file in any modern browser (Chrome, Firefox, Safari, Edge).

Features

Feature	How to use
Hover tooltip	Move the cursor over any data point to see its label and value
Click to pin	Click a point to keep it highlighted; click again or press Escape to clear
Search	Type in the search box (top-left of the plot area) to dim non-matching points; Escape clears
Coordinate readout	While the cursor is inside the plot area, the current x/y in data space is shown near the cursor
Legend toggle	Click a legend entry to hide that series; click again to show it
Save SVG	The Save button (top-right) captures the current DOM state. Download is not yet functional — will be fixed in v0.2.

Plot support

Interactivity is fully wired (hover, search, legend toggle) for:

scatter
line
bar
strip
volcano

All other subcommands accept --interactive and render the coordinate readout and search UI, but individual data points do not yet respond to hover or search. Full renderer coverage is planned for v0.2.

Non-SVG contexts

--interactive is silently ignored when:

Output is PNG (--features png) or PDF (--features pdf)
Output is the terminal (--terminal)
The SVG is opened in Inkscape or Illustrator (script tags are stripped)

Non-interactive plots are byte-identical to today — the flag is purely additive.
