Example usage

var fg = new FlamegraphView<Node>();

flamegraphView.setRenderConfiguration(
        FrameTextsProvider.of(
                frame -> frame.isRoot() ? "root" : frame.actualNode.getFrame().getHumanReadableShortString(),
                frame -> frame.isRoot() ? "" : FormatToolkit.getHumanReadable(frame.actualNode.getFrame().getMethod(), false, false, false, false, true, false),
                frame -> frame.isRoot() ? "" : frame.actualNode.getFrame().getMethod().getMethodName()
        ),
        new DimmingFrameColorProvider<>(defaultFrameColorMode.colorMapperUsing(ColorMapper.ofObjectHashUsing(defaultColorPalette.colors()))),
        FrameFontProvider.defaultFontProvider()
);

jpanel.add(flamegraphView.component);


// later, fill in the data
var listOfFrames = FrameBox.flattenAndCalculateCoordinate(new ArrayList<Node>(), ...);
flamegraphView.setModel(
        new FrameModel<>(
                "title, events (CPU, Locks)", // used in the root "frame"
                 (a, b) -> Objects.equals(a, b), // used to identify equal frames
                 listOfFrames
        )
);
