For this component, follow these recommendations on the accessibility:

• If a text metric is present next to the mini chart, and it fully represents the mini chart data, hide the mini chart from assistive technology with aria-hidden.
• If there's no accompanying text metric, or it doesn't fully represent the data, add an aria-label with a data summary for the mini chart.
• If you intend to make the mini chart a clickable element or link, enclose it in the appropriate tags (a or button). This ensures better touch target control and allows the addition of elements like text within the hover area. For links and buttons, include an aria-label unless they contain visible text readable by assistive technology.
