It has been several months since I wrote a series of articles that treated the development of dendrograms through the use of the JavaScript library D3. However, I recently received a series of requests to deepen the topic, which apparently seems to have enjoyed a fairly successful.

This article is linked to the article Hexagonal binning in which this method of aggregation of data is shown starting from a scatterplots representation and then ending with a representation that uses Hexagonal bins.

Scatterplots are a simple way to visualize the distribution of data on an XY plane, especially when we want to highlight the presence of clusters or particular trends.

Before starting with this article, I suggest you read the article Hexagonal binning, in which is explained and shown this method of aggregation. The article compares the scatterplots generated by two different sets of data. It is thus highlighted that for particular sets of data, especially those that are presented as a distribution "sparse" on the XY plane, it can be difficult to detect any clusters or linear trends.

In this article we will see how to calculate and represent in an automatic way the average and the standard deviation, the fashion and the median of a bar diagram. To do this we will use the Jqplot library.

Welcome, in this article we will see how to create a chart that represents real-time data using Jqplot library.

This is the fourth of a series of articles illustrating how to develop a dendrogram, using the D3 JavaScript Library, built on the basis of a particular data structure contained within a JSON file.

Dendrograms are a very useful graphical tool for group analysis (cluster analysis or clustering). The Dendrogram is essentially a tree graph.
