Bar Chart Component

well done a few notes though

1. you should use heading in order so h1 > h2 >h3 etc and manipulate the font size later as you want remember that the headings indicate section of your app so the page is a section and should have a name inside of h1 the card is a subsection and should have a name inside of an h2 and so on remember heading indicate the level of this section not for big font and all you landmarks must have an h2 level heading
2. make sure that all of your page is contained by a landmark examples of landmarks are

header for the top section
main for your main section
section with aria-label to describe why you added this section
footer for the bottom section
