NVD3 is a JavaScript library that extends the D3.js library

NVD3 is a JavaScript library that extends the D3.js library to make it easier to create reusable and customizable charts and graphs. D3.js (Data-Driven Documents) is a powerful library for manipulating data-driven documents. When compared to using D3.js directly, NVD3 provides pre-built chart components and configurations, making it easier to create common types of charts with less code.

Key features and components of NVD3 include:

  1. Reusability: NVD3 promotes the creation of reusable chart components, making it easy to use the same chart type with different datasets and configurations.

  2. Chart Types: NVD3 supports a variety of chart types, including line charts, bar charts, scatter plots, pie charts, and more.

  3. Responsive Design: Charts created with NVD3 are responsive by default, adapting to different screen sizes and devices.

  4. Interactive Features: NVD3 charts often come with built-in interactivity, such as tooltips, zooming, and panning.

  5. Ease of Use: NVD3 abstracts away some of the complexities of D3.js, allowing developers to create charts with less code and effort.

  6. Customization: While providing default configurations for various chart types, NVD3 allows developers to customize the appearance and behavior of charts.


Simple pie chart code is provided here:

<svg class="mypiechart" id="test1"></svg>
<script>
    var testdata = [
        {key: "One", y: 5, color: "#5F5"},
        {key: "Two", y: 2},
        {key: "Three", y: 9},
        {key: "Four", y: 7},
        {key: "Five", y: 4},
        {key: "Six", y: 3},
        {key: "Seven", y: 0.5}
    ];
    var height = 350;
    var width = 350;
    nv.addGraph(function() {
        var chart = nv.models.pieChart()
            .x(function(d) { return d.key })
            .y(function(d) { return d.y })
            .width(width)
            .height(height)
            .showTooltipPercent(true);
        d3.select("#test1")
            .datum(testdata2)
            .transition().duration(1200)
            .attr('width', width)
            .attr('height', height)
            .call(chart);
        return chart;
    });
  </script>

Three.js 3D Graphics Library

Image
Each three.js project requires at least one HTML file to define the webpage and one JavaScript file to run the three.js code. The structure and naming choices listed below are optional, but will be used for consistency throughout this guide. Three.js is a well-known JavaScript library for creating 3D graphics and animations in web browsers. It makes working with WebGL, a web standard for rendering 3D graphics, easier by providing a higher level of abstraction. Three.js is an open-source framework for creating interactive 3D experiences on the web. Here is a simple example of creating a scene 3D skeletal with a using Three.js: Example creates a rotating birds in a 3D scene using Three.js Download source code from Github Link: https://github.com/kanakaraju/ThreeJS_Easy_Tricks Please see the URL below for more animated examples using three js library https://threejs.org/

HTML Marquee

HTML Marquee : An HTML marquee is a web development element that allows text or images to scroll horizontally or vertically on a web page. However, as of my most recent knowledge update in January 2022, the <marquee> tag was deemed obsolete and should not be used in modern web development. For similar effects, CSS animations or JavaScript are frequently used. Example of an HTML marquee tag: <marquee behavior="scroll" direction="left" loop=""><img width="300px" src="images/lion.gif"></marquee> Download Source code from Github Link: https://github.com/kanakaraju/HTML_Easy_Tricks/tree/main/Marquee
