Dieter Krachtus developed Chartle starting in 2008. Its main purpose was to “allow people to create, publish, and share rich interactive visualizations online.” The design and principle purpose of Chartle is simple, allowing users to create charts stress-free. Many software’s, such as Microsoft Excel, are often complicated, giving users too much information. Chartle simplifies this information and visually gives users options that they cannot see when creating charts in other software. Chartle is hosted on the main server in the Netherlands and on Google servers in the United States to ensure availability and security.

Dieter Krachtus currently works as a senior software architect and is also pursuing a PhD thesis at the Interdisciplinary Center for Scientific Computing in Heidelberg, Germany. His goal in the next step of Chartle is to allow users to import data from software such as Excel into for users to create charts and tables based on their data. Tutorials are also going to be added to the website for the user to easily create charts stress-free.

How Chartle Works
There are two easy steps to using Chartle. The first step in using Chartle is obviously creating the chart. First, pick the type of chart. The charts available include but are not limited to pie charts, line graphs, tables, and maps.  Next, pick a title for the chart as well as fix the legend and sizing. The option of making a 3-dimensional chart exists for users to create as well. Then, add the data.  Do this by clicking the “Data” tap which is located next to the “General” tab.  The second and last step in using Chartle is publishing the chart.  First, click the “Publish, share, or embed” icon. A box will show up asking for the title of the chart, the author’s name, and a brief description of the chart. Another web page will pop up showing the successfully created and published chart. Please watch the tutorial below for further explanation.

Purpose of Chartle

The purpose of is to allow anyone across the globe to create images and interactive charts in a simple way. It can serve as an addition visual aid in a presentation, a blog, a brochure, or any other application. Just a few of the possible creations a user is able to produce through include bar graphs, pie charts, plots and diagrams, tables, timelines, gauges, and maps. takes pride in its efforts to “tear down the complexity of online visualizations” by trying to lessen the gap (between the 1 billion print publications of graphs and charts and the 40 million online) caused by that complexity. Through, users all across the globe are able to enhance previous creations in a simply and interactive way that will make an immediate impression on all others who see it. 

How Chartle Relates to Other Applications
Chartle is easily compatible with other Web 2.0 applications. It has the capability to be embedded in a website such as Facebook, MySpace, Twitter, etc. at the touch of a button. The only drawback is that it does not actually load the chart itself, only a link to the chart. Also, it is rather difficult to upload the actual chart because it cannot be copy and pasted but rather it must have a screen shot taken of it and then that must be copy and pasted onto your Website, PowerPoint, or Word document which makes the chart no longer interactive. If you have internet access on the computer you are using though, then Chartle is really easy and compatible with all of the different Microsoft Office programs and other Web 2.0 apps.

As compared to other Web 2.0 chart applications, Chartle is very easy to use and is fun and interactive. It is really easy to use in comparison to other Web 2.0 Chart applications.

Unique Ways of using Chartle
Chartle is such a unique program that allows many of its users to express themselves and their needs in many different ways. Besides the normal ways that one can express the work by using a normal chart, Chartle offers many unique ways that adds personality and variety.  Chartle offers it’s users not only the basic charts but others too. They include the following: Map charts, Google Map charts, Gauge Charts, Dynamic Charts such as annotated and Motion Charts, and so much more. These Charts differ so much from the ones that are accessible from programs such as Microsoft’s Excel program or Mac’s Keynote program. It allows the user to gain that extra edge when displaying a presentation.

Using Chartle in a Business Setting

Training purposes- get new employees prepared to work for the company. For example, within a school system, new teachers could use Chartle as a major resource in relating material to the students. Student Use: Students could use the wiki for preparation for class activities and materials. I short demo and introduction to the wiki in class, would be helpful. Students can illustrate their weekend activities within a chart from Chartle and then write an essay about their weekend, for example. The ability to use the quick and easy charting system may even help when given a research assignment to complete and illustrate their findings in a visual format. Big Business Use: Businesses could use this wiki for both training and resource use. The Chartle page would help when developing an illustration of projected numbers for the company, etc. that need to be presented to a small or large group. Other reasons for the Chartle use: Clarity, Communication, Motivation, Coordination, Creativity, Time Management, Flexibility, Manageability, Efficiency, and Accountability.


Charting Advantages: display relative proportions of multiple classes of data, size of the circle can be made proportional to the total quantity it represents, summarize a large data set in visual form, be visually simpler than other types of graphs, permit a visual check of the reasonableness or accuracy of calculations, require minimal additional explanation, and be easily understood due to widespread use in business and the media.

Charting Disadvantages: do not easily reveal exact values, many pie charts may be needed to show changes over time, fail to reveal key assumptions, causes, effects, or patterns, and be easily manipulated to yield false impressions.

Chartle is a well-designed service that lets you create bar graphs, pie charts, and line graphs. Just add data, pick your graph type, and Chartle will take care of the rest. It's a great tool.

I love a good chart. That may sound corny, but just think about how much charts help us to understand information. You can read facts and figures all day long and get a basic understanding of what the data means, but once you see everything displayed on a graphical chart, it suddenly makes a lot more sense. With a single glance, you're able to fully understand what the information means. If you need to share certain data with others, you're probably better off creating a chart than just dumping the content in a paragraph. Charts can be fun to create, but they can also be a pain. provides you with an online way to easily create charts.
With their tool, you're able to create charts whether you're a fan of the pie, bar, line, or some of the other varieties. Select the kind that you want, fill in the data, modify the appearance, and publish, share, or embed as you see fit. If you use effectively, your data is going to be a lot more convincing, professional, and appealing.

NCS-Tech Webpage It's a free, very intuitive, fast (Java-powered) website for generating embeddable graphs. All the basic types are there (line, bar, pie, etc.) along with some fun & unusual ones, like this "Google-O-Meter" (that's what they call it!):

The graphs are easily customizable, though the interface is a little funky in spots, it's still easy to use. Wish there was a way to add a title – maybe I am missing something? Best of all, no signup is required, so students can use it right away. This could be a handy way to design graphics for blog posts, wikis and other online projects. The chart is rendered via embed code but it you could also take a screenshot and then paste the resulting image, or, use right-click and save as.
It's a cool little site with neat potential in the classroom!
Hope this helps,

Personal Webpage

Chartle is a free, no registration required Web 2.0 app that allows users to create a wide variety of diagrams, maps and charts, some with unique interactive features. Objects created with Chartle can be shared or embedded in blogs or wikis. It has a many features, some of which are quite complicated. It is also a very young Beta product, and only works in Firefox 3.x on PCs and Macs. With those caveats in mind however, it is an intriguing tool with enough going for it to keep it on any tech savvy educator's radar.

Recently was voted one of the top 15 appengine apps (being the only web app based on JavaFX technology!) and got a ton of good feedback from other sites. Given that we are in early beta stage with a lot of problems and still many features to come I am very happy.
Embedding of Chartles got a whole lot easier a few days ago. Here are some Chartles published by users in our public gallery:

Chartle is a new online tool to easily and quickly make charts, graphs and maps.
It's slightly more complicated than some of the other applications on The Best Tools To Make Simple Graphs Online, but still worth adding to the list.
I learned about it through RusselTarr on Twitter.
