Users can:

• View the bar chart and hover over the individual bars to see the correct amounts for each day
• See the current day’s bar highlighted in a different colour to the other bars
• View the optimal layout for the content depending on their device’s screen size
• See hover states for all interactive elements on the page
• JSON data is used to dynamically size the bars on the chart

I learned how to write custom Tailwind classes. I had values for padding, colors, font size, font weight, and border radius that differed from TailwindCSS default styling. I extended TailwindCSS' styles in tailwind.config.js. For example:

theme: {
    extend: {
        ...
        colors: {
            'soft-red': '#EC755D',
            'cyan': '#76B5BC',
            'pale-cyan': '#B4E0E5',
        }
        ...
    }
}

To generate the height of each bar, I created a simple one-variable equation using the day amount and bar height in pixels (according to the design). Solving for x, I got the ratio to multiply each date amount and rounded up to the nearest whole number.

const barHeight = `${Math.round(props.amount * 2.8661)}px`;

Using string templates, I was able to set the height with the calculated height.

<div 
    style={{height: barHeight}}
></div>
