D3.js is a JavaScript library for producing dynamic, interactive data visualizations in Web browsers, using the widely implemented SVG, HTML5, and CSS standards. The CData API Server enables you to generate REST APIs for 80+ data sources, including both on-premises and cloud-based databases. This article walks through setting up the CData API Server to create a REST…

I have used D3 in concert with C3 to create a data visualization front end to a data warehouse.  D3 has a ton of features but is difficult to use out of the box for the novice user.  The C3 library puts a layer of smarts on top of D3 making it much easier to get started in graphic visualizations.  I’ve also used CData product to get an ODBC connection to Google sheets in order to analyze and transfer results from a Google form survey to a data warehouse.  CData products are very good just be willing to pay for that excellence.

This article is a good read because it combines the two to assemble a REST service and use it to provide the data feed to D3.

Business Intelligence comparisons done dirt cheap

The proliferation of business intelligence platforms, tools, and software stacks is dizzying. It seems that not a week goes by in which a new product isn’t introduced to the market, which grows ever more fragmented and confusing. Specialized business intelligence tools for cloud-based data visualization, Hadoop, text analytics, and other specific solutions for certain analyses…

It’s official I’m doing any more BI comparison posts.  I just can’t keep up.  I swear there is either new BI tool every week or a “New Features” post on an existing one.  Recently I did a comparison of a specific set of BI Tools requested by a State Agency.  The problem was the selected set of tools to review didn’t provide the best solution.  Now there are 19 websites with comparisons out the Yazoo and you don’t have to pay a consultant, or do you?   This week I have 2 favorites Tableau and Microsofts Power-BI.  I’m fickle so next week it may be something different.

Is it modern art or is it data?

Data visualizations on acid.  A researcher with R programming language and mortgage rates for the last 30 days took data and turned it into some form of modern art.  The whole package is available on GitHub.

Dashboards on the cheap, DIY with Gridster

Recently, I published an article on various JavaScript libraries for Dashboards. In this article, I am going to demonstrate how we can create a dashboard with drag-and-drop visuals and export it using JavaScript. I am going to use the Gridster library to create the dashboard. I have used this library in my projects and found it…

It takes a few libraries to create dashboards that look like

Gridster.JS is a jQuery plugin that when combined with Chart.JS to create the charts and jsPDF to snapshot the page into a PDF file you can build a custom dashboard quickly.  If you have used Tableau or Microsofts Power BI and wondered, “Could I write something like this in code for a specific solution”, me thinks the answer is “Yes”.
