Zaption - Interact & Learn with Video Lessons The 14 Best Data Visualization Tools Nishith Sharma is the co-founder of frrole, a social intelligence startup. Raw data is boring and it’s difficult to make sense of it in its natural form. Add visualization to it and you get something that everybody can easily digest. Not only you can make sense of it faster, but you can also observe interesting patterns that wouldn’t be apparent from looking only at stats. All Killer, No Filler This one’s different, trust us. To make the tedious task of making beautiful charts and maps easier, I’ve made the list of best data visualization tools available for the job. Let’s get started! For Developers D3.js D3.js, short for ‘Data Driven Documents’, is the first name that comes to mind when we think of a Data Visualization Software. It doesn’t ship with pre-built charts out of the box, but has a nice gallery which showcases what’s possible with D3. FusionCharts FusionCharts has probably the most exhaustive collection of charts and maps. Chart.js Google Charts Highcharts Leaflet dygraphs Datawrapper

History for Kids: Aztecs, Maya, and Inca Back to History The three most dominant and advanced civilizations that developed in the Americas prior to the arrival of the Europeans were the Aztecs, the Maya, and the Inca. Map of Aztec, Mayan, and Incan Civilizations by Ducksters Aztecs The Aztec Empire was located in central Mexico. It ruled much of the region from the 1400s until the Spanish arrived in 1519. The capital city of the Aztec Empire was Tenochtitlan. The Aztec called their ruler the Tlatoani. Maya The Maya civilization began as early as 2000 BC and continued to have a strong presence in Mesoamerica for over 3000 years until the Spanish arrived in 1519 AD. The Maya were located in Central America in a region that is today made up of southern Mexico, the Yucatan Peninsula, Guatemala, Belize, and northern El Salvador. The Maya were the only American civilization to develop an advanced written language. Inca The emperor of the Inca was known as the Sapa Inca. ActivitiesCrossword PuzzleWord Search

HISTORY OF THE INCAS Cuzco and the Incas: 15th century In the early 15th century the town of Cuzco is a small place, the headquarters of one of many competing tribes within the region which was once ruled from Tiwanaku. But in about 1438 a younger son of the ruler defeats the neighbouring Chanca people, usurps power, gives himself the resounding title Pachacuti ('transformer of the earth') and begins an astonishing process of military expansion. The policy is continued by his son, Topa Inca (also sometimes called Tupac Inca). By the end of two long reigns (about fifty-five years in all) the Cuzco dynasty, known as the Incas, are in loose control of an empire stretching from Quito in modern Ecuador to the Maule river in Chile - a distance of nearly 2500 miles. Even allowing for the exaggerations of oral history transmitted within a ruling dynasty, this is a remarkable achievement. The Inca expansion also shares some features with Genghis Khan's programme of conquest. Inca roads: 15th century

Incas - HowStuffWorks Incas, an Indian people of South America. Long before the voyages of Columbus, their empire, centered in Peru, was remarkable for its organization and culture. The word Inca, properly the title of the emperors, was eventually applied to the people as a whole. Their descendants, the Quechua Indians, now make up most of the rural population of Ecuador, Peru, Bolivia, and parts of Argentina. The Inca Empire stretched 3,000 miles along the coast of South America. At its height the Inca empire stretched for some 3,000 miles (4,800 km) from present-day Colombia along the Pacific coast through Ecuador, Peru, and Bolivia into Chile. How the Incas Lived The Incas worshiped the sun god, Inti.His chief temple, the Temple of the Sun, was radiant with the immense amount of gold, silver, and jewels used to decorate it. The Inca emperor, believed to be descended directly from the sun god, had absolute power. Inca emperors were treated as earthly gods. The Incas spoke the Quechua language. History

Prehistoric Inca neurosurgery – Neurophilosophy The procedure known as trepanation, in which a hole is scraped or drilled in the skull, is an ancient form of neurosurgery that has been performed since the late Stone Age. Exactly why ancient peoples performed trepanation has remained a matter of debate: some researchers argue that it was performed for medical reasons, as it is today, while others believe it was done for magical or religious reasons. A new study by two American anthropologists now provides evidence that the Incas performed trepanation to treat head injuries; that the procedure was far more common than was previously thought; and that the Incan practitioners of trepanation were highly skilled surgeons with a detailed knowledge of the anatomy of the skull. Of these 411 skulls, 66 exhibited perforations of varying shape and size. More than half were circular, but some were oval or irregularly circular, and one (above) was rectangular. The diameters of the circular holes ranged from approximately 0.3 – 7.3 cm.

Exploring the Inca Heartland: Machu Picchu We wandered down a long stretch of Inca road from the Sun Gate, enjoying the view of the site below us and feeling good about having hiked the Inca Trail. To us, it seemed that slogging over the passes and heights had earned us more of a right to be there than the bus loads of tourists who were driven there from Cusco. We looked about for awhile, then continued down to our campsite in the valley below. We were all blown out and rather grotty, so a trip to the natural hot baths at Aguas Calientes was in order, followed by dinner at one of the local restaurants near the train tracks. How lost was Machu Picchu, the lost city of the Inca? It does appear that no Spanish artifacts have been found in solid contexts at Machu Picchu either by Bingham or the recent Peruvian excavations directed by Julio Tello. In the morning we hopped on a local bus up to Machu Picchu, entering the site early, before hordes of tourists like us clogged up the place. Machu Picchu was (and is) not a large site.

The Incas The Incas The Incas, an American Indian people, were originally a small tribe in the southern highlands of Peru. In less than a century, during the 1400s, they built one of the largest, most tightly controlled empires the world has ever known. Social Order To fully appreciate the Inca achievement, it helps to visualize the difficult terrain of western South America. The Empire The basic unit of Inca society was the village, or neighborhood, in which the residents thought of each other as at least distantly related. The Emperor. Established custom guaranteed that the emperor behave responsibly. Nobles. The four nobles who governed the four quarters of the empire served as the emperor's council. Language. Way of Life There are many gaps in our knowledge of Inca life. From these we know that most Incas lived in villages. Dress. Food. Work. Some workers tended flocks of llamas. Shelter. Religion The most sacred shrine in Peru was the Temple of the Sun, in Cuzco. Feasts and the Calendar.

Inca mathematics Version for printing It is often thought that mathematics can only develop after a civilisation has developed some form of writing. Although not easy for us to understand today, many civilisations reached highly advanced states without ever developing written records. Now of course it is difficult for us to know much about such civilisations since there is no written record to be studied today. This article looks at the mathematical achievements of one such civilisation. The civilisation we discuss, which does not appear to have found a need to develop writing, is that of the Incas. The quipu was not a calculator, rather it was a storage device. The quipu consists of strings which were knotted to represent numbers. 586 on a quipu. For larger numbers more knot groups were used, one for each power of 10, in the same way as the digits of the number system we use here are occur in different positions to indicate the number of the corresponding power of 10 in that position.
