Enabling "aria.enable" to generate aria-label for accessibility

[hazren-sulaiman]

Hi, is there a way to enable "aria.enable" in order to generate "aria-label" for accessibility? This will be useful for screenreader to describe the chart.

This is not supported currently. However, you can append additional JSON to the generated output via new addCustomEncoding methods added recently in version 3.2.5.

        SOChart soChart = new SOChart() {
            @Override
            protected void addCustomEncoding(ComponentPart componentPart, StringBuilder buffer) {
                if(componentPart == null) {
                    buffer.append("""
                            "aria": {
                                "show": true
                              },
                            """);
                }
            }
        };
