The Google Chart API lets you dynamically generate charts with a URL string and embed these charts on a web page, or download the image for local or offline use. The Google Chart Tools enable adding live charts to any web page. They provide advantages such as a rich gallery of visualizations provided as image charts and interactive charts and they can read live data from a variety of data sources.
Users embed the data and formatting parameters in an HTTP request, and Google returns a PNG image of the chart. Many types of chart are supported, and by making the request into an image tag the chart can be included in a web page.
Many APIs eventually find their way to the ProgrammableWeb deadpool. They end up there for various reasons: no business model, replaced by a newer service or ceased being useful. The most popular of these dead APIs are predominantly from two big tech firms: Google and Yahoo. Search and mapping make up the bulk of the functionality behind these 12 popular--but no longer available--APIs.
Our API directory now includes 39 barcode APIs. The newest is the Barcodes4.me API. The most popular, in terms of mashups until it was deprecated last Fall, is the Google Chart API. We list 87 Google Chart mashups. Below are some stats from the directory, including the entire list of barcode APIs.
The news of data visualization provider Tableau's IPO on Friday is yet another sign that the movement behind data and analytics continues to gain steam. With that in mind, today we'll take a look at recent mashups that allow users to perform data analytics of some kind and often show the results through interesting visualizations. Read below for more information on each.
A quick glance at the latest API house-cleaning from Google might lead you to believe they're discontinuing some of their most popular APIs. The changes to the Google App Engine API and YouTube API, among others, are likely just formalities of moving to a single terms of service. However, there are some APIs marked for deletion by the search giant, including the popular Google Chart API.
Google Chart Tools is the search giant's bundling of the Google Chart API and Google Visualization API. These tools create the perfect means for businesses and students to visualize data on websites as well as other types of presentations.
Each of Google's 95 APIs has employees to support it. So, we're used to seeing tutorials from Googlers about this API or that. Last week the search giant did something different. In a series of posts, Silvano Luciani wrote a series of posts showing how the Google Chart API can help make sense of data from the Google AdSense API.
