In the introductory series of tutorials, we often use the D3.json () function to read JSON-formatted files. The JSON format is powerful, but for ordinary users it may not be appropriate for ordinary users to prefer a form file generated with Microsoft Excel or OpenOffice Calc, because it is easy to understand and easy to edit.Microsoft Excel is typically saved in the XLS format, and OpenOffice Calc is typically saved as an ODS format. These formats ar

Learn about graphical calculations for the components used to draw various permutations The 1th part of this two-part series outlines the combined use of SVG and D3, providing some basic examples of creating browsing data visualization representations of social media. Part 2nd will describe the steps for arranging or laying out different graphic components in SVG graphics. You will learn how to use D3 powe

The 3rd section makes an icon, but does not add a corresponding axis for it, so you don't know how long each bar is. This section makes an axis.The axes in D3 are in the form of SVG diagrams, which is why the method of SVG is used in the 3rd section to do column charts. In the 4th section, we explain the usage of scale, and we need to use the scale when we do the axes. In the 4th section, we say that scale is a function, and the axes in this section a

Color interpolation refers to the given two RGB color values, the values between two colors are calculated by the interpolation function. A linear gradient is a filter that is added to an SVG graphic by simply giving the color values at both ends. 1.

D3 is widely used and is now one of the mainstream data visualization tools. Everyone in the first contact with the use of d3.js, the most difficult place is data (), enter (), exit () these several operations.

In the "Getting Started-10th chapter" made a map of China, in which the color values of the provinces are randomly assigned values. If you want to reflect some values on the map, you can use the color changes to represent the change in values.1. IdeasFor example, a range of domains is:[10, 500]It is hoped that 10 with light green, 500 with dark green, 10 to 500 between the value of light green and dark green between the color expression. Obviously, a function is needed here, the passed-in parame

for each region: DX and dy. Used to save offsets.2. Definition of the Drag eventEach time the drag event is triggered, we just need to get the mouse offset and add it to the original offset dx and dy.Then use D3.select (this) to select the current element and apply the transform to it to complete the panning operation.var drag = D3.behavior.drag (). Origin (function (d) {return D;}). On ("Drag", DragMove),

Most of the data bound in D3 is done by the function, how does it work, and how does it differ from datum ()?The data () function can bind array items to each element individually, and can set rules for binding. Data () can also handle cases where the length of the array is inconsistent with the number of elements. When the array length is greater than the number of elements, the element position can be reserved for extra data so that new elements can

In the previous chapter, we used a very important concept-scale, which explains how to use this section.1. Maximum value and minimum valueBefore introducing the scale, we introduce two functions that appear together with the scale bar, and also appear in the "3rd chapter". D3.max () D3.min () These two functions are used to find the maximum and minimum values in an array, and if it is a on
