Visualize Your Data And Speed Up Your Site With Dynamic Chart Libraries

Create a data visual interface that combines aesthetics and efficiency

Designers should strive to create interfaces that are not only visually attractive, but also flexible and efficient. Data visualization should strike a balance between aesthetics and practicality.

Dynamic chart library provides a practical solution for data visualization, allowing real-time updates, interactivity, and significantly reducing page loading time for a smoother user experience.

There are a variety of dynamic chart libraries to choose from, each with its pros and cons, including HighCharts, PlotKit, d3.js, FusionCharts, Google Chart Tools, and Flot. These libraries range from simple, free to powerful and expensive.

Dynamic chart library can handle large amounts of data, support various chart types, and provide a range of customization options. Most are designed to work with multiple programming languages ​​and come with comprehensive documentation and examples to help users get started.

In previous articles, we delved into dozens of aesthetic topics, but design work is not always pure aesthetic. Often, “well-designed” solutions are not only visually attractive, but also flexible and efficient. Sometimes, focusing only on the visual appearance and ignoring all other aspects of the project can result in the design looking beautiful but not practical. One example is high heels; it may look stylish and attractive, but for women who have to wear it, it hurts feet, is useless on the soft ground, and cannot run. If you take a similar approach to your design project, you may end up with a design that is like high heels, all stylish with few features. To ensure that your next interface or login page design doesn’t encounter the same fate as you choose the wrong footwear, you may need a way to visualize your data and strike a cautious balance between aesthetics and practicality. The designer’s first instinct might be to use Photoshop or Illustrator to make pixel-perfect graphics or charts, but this solution requires constant updates to the charts, and this approach is far from simple and practical even if the data changes minimally. If your metric changes only a few units or percentage points, you may have to open an editable file, make the required changes, export and upload a static image every time. For such a small change, this requires a lot of work. Worse, if your data is based on a timeline or other changing metrics, your chart is actually outdated every day. Finally, static images are ultimately not interactive, which makes you inefficient in utilizing programming knowledge and website interaction capabilities.

Charts that combine beauty and practicality

So instead of sacrificing all practicality (and interactivity) for perfect charts, use a dynamic chart library. These chart libraries can display charts that look amazingly, while staying flexible and easy to update, making them an excellent solution for designers and general audiences. Some of these libraries rely on HTML5, which is not entirely supported by older browsers, but these compatibility issues are quickly disappearing with each new browser update. Dynamic charts are also much smaller and much lighter than large image files, which provides an additional advantage in website speed. The advantages of using dynamic chart libraries are increasing, while their potential problems are decreasing. There are many libraries to choose from, all of which have unique advantages and disadvantages.

HighCharts

3 different ways to view fruit consumption data using HighCharts

HighCharts is a JavaScript-based chart library with stylish charting, excellent support and impressive compatibility. You can rely on their charts to run in every browser from the annoying Internet Explorer 6 to the latest version of mobile Safari in iOS devices. Their charts also feature subtle animations—the growth of bar charts and the tracking of trend lines—adding their visual appeal. The library is open source, so the chart can be modified based on the unique needs of any project. HighCharts is free for non-commercial use, but for commercial projects, it has considerable costs. For a single website, it costs only $80 to use HighCharts, but for a team of 10 developers to use the library in multiple projects, the price jumps to $2,000. If you are using HighCharts in your application, you must contact the manufacturer to negotiate the price and use of HighCharts.

PlotKit

Three charts rendered with PlotKit

PlotKit's chart may not be as attractive as HighChart's chart, but PlotKit is 100% free in all cases. It also has a useful quick start guide that can help you run the charts. PlotKit detects whether the visitor's browser supports , and if it is found, use this technology. Otherwise, it has a fallback method for older browsers to achieve the same purpose. PlotKit is not a standalone library; it relies on MochiKit to work properly, which can make installation and maintenance slightly more difficult than standalone libraries.

d3.js

d3.js is a JavaScript-based drawing library with clear aesthetics in file sizes and a high value for its zero-dollar price tag. d3.js is an excellent choice for visualizing large amounts of complex data. The charts are brightly colored and clear, and the documentation is detailed and practical. d3.js emphasizes interactive motion-based transformations, which can add impressive functionality to charts in web design. The manufacturer of d3.js has tutorials to help new users get started and rich documentation for senior users.

FusionCharts

Nine different charts using FusionCharts

FusionCharts has a large number of chart types, all of which have a polished, professional style. They also have hundreds of features, and they provide extensions to software like Powerpoint, Joomla, Dreamweaver, and Flex. However, all of these tools are paid, with the licensing fee of FusionCharts up to $10,000, making this option only suitable for projects with a well-budget and needing to display a lot of data.

Google Chart Tools

Some of Google's versatile charting tools

Google provides their own chart library in the form of Google Chart Tools. As you would expect from Google, these charts have an intuitive, familiar look and are as easy to set up as viewing and analyzing. Google Chart Tools takes advantage of the hover effect; hovering over the data type in the chart legend usually highlights the corresponding part of the chart or graph. After including the necessary code snippets to your website, drawing (or updating) chart data is as simple as inserting comma-separated text values, as shown in the code example below, which contains the consumption of pizza slices by ingredients:

<code class="language-javascript">// 创建数据表。
var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');
data.addRows([
['Mushrooms', 3],
['Onions', 1],
['Olives', 1],
['Zucchini', 1],
['Pepperoni', 2]
]);</code>

While your chart will depend on external files, these files are hosted on a reliable Google server, minimizing your concerns about chart disruptions or other technical issues.

Flot

Flot's chart is simple, clear and clear

Flot is different from the above chart library because it is designed for use in JQuery, not just JavaScript. This may make it the first choice for JQuery experts who want to overcome the learning curve as quickly as possible. As you would expect from JQuery products, Flot does a great job of making the chart interactive. You can use the "X" and "Y" axes to form crosshairs that follow the cursor, and you can also use a simple form to turn data on and off in a graph or chart. For greater interactivity, you can export dynamic graphics as static PNG or JPEG image files.

Conclusion

From the above options, hopefully at least one chart library can make your data-based design work both beautiful and practical. They range from simple, free to powerful and expensive. Familiar with dynamic charting tools may save a lot of time in the long run, otherwise this time will be used to make tiny, tedious corrections to static images. Do you have any chart library or drawing tool that you can recommend? Or, what are the advantages of static images that make it the best tool for visualizing data?

Frequently Asked Questions about Dynamic Chart Library

What are the benefits of using dynamic chart libraries?

The dynamic chart library provides a range of benefits. They allow real-time data visualization, which is crucial in today's fast-paced digital world.
