Installing Necessary Packages

To begin, we need to install several required modules. You can do this by executing the following command:

npm install @visx/gradient @visx/group @visx/mock-data @visx/responsive @visx/scale @visx/shape

Creating Pie and Donut Charts

We can generate pie and donut charts through the following code snippet:

import React, { useState } from "react";

import Pie from "@visx/shape/lib/shapes/Pie";

import { scaleOrdinal } from "@visx/scale";

import { Group } from "@visx/group";

import { GradientPinkBlue } from "@visx/gradient";

import letterFrequency from "@visx/mock-data/lib/mocks/letterFrequency";

import browserUsage from "@visx/mock-data/lib/mocks/browserUsage";

import { animated, useTransition, interpolate } from "react-spring";

Here, we define variables for letters and browser names, which are derived from mock data. This data will be used to render our charts.

The video titled "Pie Charts in React with visx" provides a comprehensive overview of how to create pie charts using the Visx library, making it an excellent resource to accompany this guide.

Next, we create color scales for the pie and donut charts:

const getBrowserColor = scaleOrdinal({

domain: browserNames,

range: [

"rgba(255,255,255,0.7)",

"rgba(255,255,255,0.6)",

"rgba(255,255,255,0.5)",

"rgba(255,255,255,0.4)",

"rgba(255,255,255,0.3)",

"rgba(255,255,255,0.2)",

"rgba(255,255,255,0.1)"

]

});

We also set up state management to track user selections for browsers and letters:

const [selectedBrowser, setSelectedBrowser] = useState(null);

const [selectedAlphabetLetter, setSelectedAlphabetLetter] = useState(null);

The Example component serves as the main container for our charts, where we compute dimensions for rendering based on the provided width and height.

The following code snippet illustrates how we render the pie and donut charts:

<Group>

<Pie

data={browsers}

pieValue={usage}

outerRadius={radius}

innerRadius={radius - donutThickness}

cornerRadius={3}

padAngle={0.005}

>

{(pie) => (

// Render logic for pie chart

)}

</Pie>

<Pie

data={letters}

pieValue={frequency}

pieSortValues={() => -1}

outerRadius={radius - donutThickness * 1.3}

>

{(pie) => (

// Render logic for donut chart

)}

</Pie>

</Group>

In this setup, we utilize the AnimatedPie component to add animations to our charts.
