Organizations that have adopted graph databases cite high performance as the technology’s top benefit, according to the “State of Graph Databases” study, which IBM released today. IBM worked with the ...

Google popularized the term "knowledge graph" in this 2012 blog post. Since then, there has been a massive momentum around ...

Speed-time graphs show speed on the vertical axis and time on the horizontal axis. The gradient of a speed-time graph represents acceleration because: gradient = \( \frac {\text{change in y ...

Plot them on a graph showing your speed on the vertical axis and your finishing time on the horizontal axis, as I’ve done below with my best 1,500, 3,000, and 5,000-meter times.

The cart then detects motion over these lines to give position-time data. Again using the quadratic fit I can find the acceleration. In this case it gives a value of 0.1092 m/s 2 .

Visualizations can help you understand data better – but they can also confuse or mislead. Here, some tips on what to watch out for. 3 questions to ask yourself next time you see a graph, chart ...

Until the nineteenth century, Friendly and Wainer tell us, most modern forms of data graphics—pie charts, line graphs, and bar charts—tended to have a one-dimensional view of their data ...

A negative gradient shows the rate of “slowing down” or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The ...
