Altair is a declarative statistical visualization library for Python, based on Vega-Lite. It provides a high-level API for creating complex visualizations with minimal code. Please include code and sample data in your question.

Altair is a statistical visualization library in Python. It is a declarative in nature and is based on Vega and Vega-Lite visualization grammars. It is fast becoming the first choice of people looking for a quick and efficient way to visualize datasets. If you have used imperative visualization libraries like matplotlib, you will be able to rightly appreciate the capabilities of Altair.

Note- Jupyter Notebook should be used to execute the code as the visualizations require a Javascript frontend to display the charts. You can refer the following article to know how to use Jupyter Notebook: Getting Started with Jupyter Notebook. You can also use JupyterLab, Zeppelin or any other notebook environment or IDE with notebook support.

The dataset is the first argument that you pass to the chart. Data in Altair is built around the Pandas Dataframe so the encoding becomes quite simple and it is able to detect the data types required in the encoding but you can also use the following for the data:

Some basic marks include area, bar, point, text, tick and line. Altair also provides some compound marks like box plot, error band and error bar. These mark methods can also accept optional arguments like color and opacity.

One of the most important things in visualization is the mapping of data to the visual properties of the chart. This mapping in Altair is called encoding and is carried out through the Chart.encode() method. There are various types of encoding channels available in Altair: position channels, mark property channels, hyperlink channels, etc. Out of these the most commonly used are the x(x-axis value) and y(y-axis value) from position channels and color and opacity from mark property channels.

In this example, we will visualize the iris dataset from the vega_datasets library in the form of a scatter plot. The mark method used for scatter plot in this example is mark_point(). For this bi-variate analysis, we map the sepalLength and petalLength columns to the x and y axes encoding. Further, to differentiate the points from each other, we map the shape encoding to the species column.

Thanks so much for the help thus far, unfortunately altair is just out of the range of my current skillset so I will have to find another solution. I also thought that the data would automatically scale, but nope.

American companies that have relied on SAS-based data analytics routines for decades but would like to separate themselves from the SAS Institute and its maintenece fees may be interested in another SAS runtime option that recently became available from Altair.

But that analytic hegemony has been tested in recent years thanks to the rise of open languages like Python and R. The meteoric rise of Python, in particular, has many companies casting their analytic bets with the uber popular scripting language, which can be used to program a slew of data-related tasks, including data engineering, analytics, and AI.

However, by all accounts, there remains a sizable group of SAS customers with large amounts of SAS code that has not been moved into Viya. Much of this SAS code has run reliably for decades on platforms ranging from Windows desktops to giant IBM System Z mainframes and Power servers. In many cases, the original SAS developers have long since left the companies, leaving efficient and reliable SAS code as their legacy.

Eventually, World Programming began selling to companies in Asia who wanted an alternative to the official runtime from SAS. Hundreds of companies in Europe and Asia eventually were users of the SAS runtime alternative.

When customers do run into unsupported procedures, the WPS team typically will work to support it in the compiler and runtime, Do Couto said. That has been the World Programming business model for years.

The savings that customers can get by moving to the WPS environment and eliminating the SAS maintenance fees is one thing. But such a move can also free up SAS code to run on bigger, newer machines that customers have been hesitant to install for fear of triggering even bigger price increases, according to Do Couto.

The ability to essentially copy and paste that aging SAS code into a new runtime and get out from under the obligation of paying SAS maintenance fees is likely to be something that SAS customers give some thought. Many will likely stay with SAS, which has made some enhancements to the language but is really focused on getting customers to move to Viya. For others, a move away from SAS may be the right one.

At the end of the day, the SAS legacy will stand as one of the greatest in the history of data analytics. But as Dr. Goodnight nears retirement, there are questions about what will become of the company that he has successfully led for so many years. No matter how solid the SAS products are, the tide of open source analytics, and Python in particular, are pulling against the company. How long will that last? Only time will tell.

But thanks to its acquisition of World Programming, Altair is positioned to let customers continue to run their SAS code, or transition to newer coding environments. Giving customers a choice in analytics environment makes good business sense for Altair and its customers, Do Couto said.

Altair BASIC is a discontinued interpreter for the BASIC programming language that ran on the MITS Altair 8800 and subsequent S-100 bus computers. It was Microsoft's first product (as Micro-Soft), distributed by MITS under a contract. Altair BASIC was the start of the Microsoft BASIC product range.

Bill Gates recalls that, when he and Paul Allen read about the Altair in the January 1975 issue of Popular Electronics, they understood that the price of computers would soon drop to the point that selling software for them would be a profitable business.[7] Gates believed that, by providing a BASIC interpreter for the new computer, they could make it more attractive to hobbyists. They contacted MITS founder Ed Roberts, told him that they were developing an interpreter, and asked whether he would like to see a demonstration. This followed the questionable engineering industry practice of a trial balloon, an announcement of a non-existent product to gauge interest. Roberts agreed to meet them for a demonstration in a few weeks, in March 1975.

Gates and Allen had neither an interpreter nor even an Altair system on which to develop and test one. However, Allen had written an Intel 8008 emulator for their previous venture, Traf-O-Data, that ran on a PDP-10 time-sharing computer. Allen adapted this emulator based on the Altair programmer guide, and they developed and tested the interpreter on Harvard's PDP-10. Harvard officials were not pleased when they found out, but there was no written policy that covered the use of this computer.[8] Gates and Allen bought computer time from a timesharing service in Boston to complete their BASIC program debugging. When fellow Harvard student Monte Davidoff stated he believed the system should use floating-point arithmetic instead of the integer arithmetic of the original versions, and claimed he could write such a system that could still fit within the memory limits, they hired Davidoff to write the package.

The finished interpreter, including its own I/O system and line editor, fit in only four kilobytes of memory, leaving plenty of room for the interpreted program. In preparation for the demo, they stored the finished interpreter on a punched tape that the Altair could read, and Paul Allen flew to Albuquerque.

While on final approach into the Albuquerque airport, Allen realized that they had forgotten to write a bootstrap program to read the tape into memory. Writing in 8080 machine language, Allen finished the program before the plane landed. Only when they loaded the program onto an Altair and saw a prompt asking for the system's memory size did Gates and Allen know that their interpreter worked on the Altair hardware. Later, they made a bet on who could write the shortest bootstrap program, and Gates won.[9][10]

Roberts agreed to distribute the interpreter. He also hired Gates and Allen to maintain and improve it, causing Gates to take a leave of absence from Harvard. The original version would retroactively be known as 4K BASIC when they added upgraded versions, including 8K BASIC, Extended BASIC, Extended ROM BASIC, and Disk BASIC.
