Power BI for Office 365 allowed users to model and analyze data, and query large datasets with complex natural language queries. It has been discontinued in favor of other editions of Power BI going forward.
It is well suited for projects that are more discovery related. If this is a one-time project that we create a visual for, this would definitely make sense to use. If this is an ongoing analysis (monthly for example), we might look to another software that we would be able to automate a little further in how the visualization comes together
If you're already using Office 365, Power BI for O365 is an easy choice. Start playing around with the free version and then easily add individual Pro licenses with little risk. However, if you anticipate using this with many users, it can get expensive quickly.
In comparison to other tools such as GraphWiz or Circos, Gephi comes with an intuitive, easy-to-use interface that makes it easy to load your data, and quickly start building all sorts of different graphs. There's absolutely no code that needs to be written for either loading or modeling. And without downloading additional plug-ins, Gephi ships with quite a few standard graph models, as well as some "fun" extras such as the Sierpinski triangle, and a variety of force atlas types.
Most of the layout types (maybe all) are highly configurable, which can make for extremely customized and unique displays of your data. Again, none of this requires the user to write any code. That said, it is possible to script custom functionality for your models, or even update the Java source code yourself, if you feel like getting technical. Gephi builds are available on GitHub, and the developers encourage people to contribute ideas, improvements, and plug-ins.
There's a plug-in for Gephi that allows for streaming data to update your model. This essentially allows you to create near realtime graphs of your data in motion. This plug-in was by far the biggest reaston we invested time in the product; to create animated data visualizations without exhaustive hours in development.
Easy to make visual dashboards from SQL queries. Previously we had to use a third party application that had to run on a web server that was so complex to setup and run. PowerBI removes all that.
Ability to control who/which group has access to each dashboard or report. Ties in well with the rest of the Office 365 ecosystem.
Has many connectors to allow pulling data from various systems, both onsite (via gateway) or external (via APIs), and join the data to create a report/dashboard.
Ability to show data but also export the data, if permitted.
Easy to show PowerBI dashboards on SharePoint or on other websites via embedded code.
I (and many others) have had to expand Gephi's memory manually by experimenting with the configuration file. I'm glad it's possible, but it should be easier.
Gephi sometimes crashes inexplicably and loses your work, so I have developed a habit of explicitly exporting versions of my graphs as csv's, but I think this should be handled automatically in Gephi.
Because it is prone to crash, ideally, Gephi would help the user manage his/her use, by estimating processing and memory for very large tasks and prompting the user to confirm their requests before executing. Instead, I just tend to avoid certain functions.
Licensing: Currently, Microsoft has a fixed pricing model for Office 365 users, regardless of role/function of the user. Most organizations have a small number of "power users" that create usable content and many more "consumers" that simply view/run reports created by power users. Microsoft does not differentiate between these users, and thus the pricing limits organizations from large deployments of the software.
Version incompatibility: Excel 2010 and 2013 workbooks are compatible with each other. However, workbooks created in 2010 that include PowerPivot databases must be upgraded to 2013 format to run in 2013. Subsequently, you cannot open these upgraded PowerPivot workbooks in 2010. This requires ALL users to be on the same version.
Visualization: Excel charting with PowerPivot workbooks is adequate for many users. Power View also contains a number of GREAT visualizations, including animated bubble charts and a very flexible dashboard/report design canvas. However, compared to some of the other self-service BI solutions, it is still limited in its visualization capabilities.
While Gephi isn't perfect, it's a powerful tool for mathematical graph modelling that's hard to find in other products, particularly by way of its interface. It grants non-software developers access to a point-and-click way of creating accurate, beautiful visualizations that would normally take hours in other applications. The fact that it allows for live streaming data is also something that's hard to come by, at least for visualization software
I will continue to recommend this suite to folks looking for a reporting and analytics solution, as I find in MOST cases, it's great at meeting almost every requirement I've been given by a multitude of clients across a range of industries. I've built Capacity Planning solutions that allowed end user input which was then submitted to SharePoint, Executive Dashboards, custom applications, simple analytical tools for teams to easily slice and dice data, and super simple reports as well as some very complicated ones. If you haven't seen the demos online, do a search, and see for yourself - this is a great BI suite! (I do not work for Microsoft, although I do consult out there from time to time. I do occasionally make a recommendation for a different BI reporting tool, but in general, find Excel can accomplish quite a bit for less money and in less time.)
Gephi is very intuitive and the fact that it shows its process helps the user understand what's going on. However, the animation features can really slow it down and there isn't a way to shut them off. Furthermore, the failures on saving mean you frequently have to start over. These problems disrupt the workflow and can be frustrating.
We are satisfied with the functionality and capabilities of Power BI. Product is cost effective and full-fill the reporting requirements of the organization. You can perform most of the report level complex analysis with the help of DAX which makes Power BI very powerful analytic tool. Power BI for Office 365 has gone away and Power BI is the next evolution of it. Power BI comes with your Office 365 E5 subscription or you can purchase licensing for it separately.
as of now there is strong community for Power BI, you can get solution for most of your problems from there. Also you can send your error to Microsoft as well. After every 15 days they release updates to overcome all the issues of defects.
The interactivity in Gephi and the quality of the output figures are impressive. However, the selling point was the fact that we were able to link Gephi into our pipeline using Java's interface. Other products were less customizable and lacking of the sophistication Gephi provided without too much pain during the liking process.
Oracle was nice, super expensive to implement if it's not in use already. JobDiva is choppy and heavy on the system while does not give great reports. Salesforce is good; remote access is good however their support is terrible
I have only used the product for education purposes. I will not be the best person to provide details about ROI and business efficiency and customer service. I was personally very excited about the tool and am continuing my work on the tool.
As a Microsoft Partner implementing Business Intelligence solutions, Power BI has removed the barrier for our clients to begin the "BI journey". So often, projects get hung up in that early phase of procuring and installing/configuring expensive hardware and software. Just simply getting started and designing a beginning solution has allowed our clients to see results in 1-2 weeks using their data that might have taken months to achieve otherwise.
One significant ROI example is process improvement. In many cases, individuals or teams are spending days each month gathering data from multiple sources for reporting to their constituents. We are reducing these times to minutes by automating many of the data collection and integration processes that were previously manual.
