D3.js vs Highcharts vs Plotly: What are the differences?
Introduction
D3.js, Highcharts, and Plotly are all popular JavaScript libraries used for creating interactive and dynamic data visualizations on websites. While they share some similarities, there are key differences between them that make each library unique and suitable for specific use cases. In this Markdown code, we will provide a concise description of the key differences between D3.js, Highcharts, and Plotly.
-
Data Binding and DOM Manipulation:
D3.js, being a low-level library, gives developers complete control over data binding and DOM manipulation. It allows for fine-grained control over how data is mapped to visual elements and enables the creation of custom visualizations with ease. On the other hand, Highcharts and Plotly provide a higher-level API that abstracts away the details of data binding and DOM manipulation, making it easier to create standard chart types quickly.
-
Chart Types and Customizability:
Highcharts offers a wide range of pre-built chart types out-of-the-box, including bar charts, line charts, pie charts, etc. It provides extensive customization options, allowing developers to tweak various aspects of the chart's appearance and behavior. Plotly also offers a good selection of chart types and customizability options, but it goes a step further by providing interactive charts that support zooming, panning, and hover interactions. In contrast, D3.js does not come with built-in chart types but instead provides a powerful set of tools for creating custom visualizations from scratch, giving developers the most flexibility and control over every aspect of the chart.
-
Learning Curve and Ease of Use:
D3.js has a steeper learning curve compared to Highcharts and Plotly due to its lower-level nature. It requires a deeper understanding of JavaScript and SVG (Scalable Vector Graphics), but it offers the most flexibility and customization options. Highcharts and Plotly, on the other hand, have a more intuitive and beginner-friendly API, making them easier to learn and use out-of-the-box, especially for developers who are not well-versed in JavaScript or data visualization concepts.
-
Interactivity and User Interaction:
Plotly shines in terms of interactivity and user interaction. It offers fully interactive charts that support zooming, panning, hovering, and tooltips by default. Highcharts also provides interactive features but not to the same extent as Plotly. D3.js, being a low-level library, requires developers to manually implement interactivity features, although it provides the necessary tools and flexibility to achieve any desired interactive behavior.
-
Community and Support:
D3.js has a thriving community and a vast ecosystem of plugins and resources available. It has been around for a longer time and is widely adopted, making it easier to find help and examples online. Highcharts also has a large and active community but not as extensive as D3.js. Plotly, although relatively newer than the other two, has gained popularity in recent years and has an active community as well.
-
Licensing:
D3.js is an open-source library released under the BSD 3-Clause License, allowing developers to use it freely and modify its source code. Highcharts, on the other hand, is available for free for non-commercial use but requires a commercial license for commercial projects. Plotly offers both open-source and commercial licenses, giving developers the flexibility to choose based on their requirements.
In summary, D3.js provides complete control and customization options, suitable for creating highly custom visualizations, but with a steeper learning curve. Highcharts offers a wide range of pre-built chart types and customization options, making it easier to create standard charts quickly. Plotly excels in interactivity and provides fully interactive charts with zooming, panning, and hover features, offering an intuitive experience for users. The choice between these libraries depends on the project requirements and the developer's comfort level with customization and interactivity.
