Chiasm Boilerplate
Raw
README.md

Boilerplate starter code for Chiasm.

To get started, go ahead and edit this example on blockbuilder.org. From there you can experiment with creating your own Chiasm components and applications, then publish your work back to bl.ocks.org.

The Chiasm components demonstrated here are:

  • chiasm-layout A Chiasm plugin for nested box layout. You can use this plugin to impose a grid system of rectangles on any collection of Chiasm components.

  • coloredRectangle An example custom Chiasm component that draws a colored rectangle using D3.js and SVG. The naming convention of my for the component is inspired by the wonderful piece on reusable D3 charts Towards Reusable Charts.

For a more complex example that creates data visualizations, check out Fundamental Visualizations.

coloredRectangle.js
// This function defines a Chiasm component that draws a colored rectangle using D3.js.
function ColoredRectangle() {
// Construct a Chiasm component instance,
// specifying default values for public properties.
var my = new ChiasmComponent({
// The color of the rectangle, a CSS color string.
color: "white"
});
// Initialize an SVG Group element for containing this component.
var svg = my.initSVG();
// Add a background rectangle to the SVG Group element using D3.
var rect = d3.select(svg).append("rect");
// Set the rectangle color to be the configured color.
my.when("color", function (color){
rect.attr("fill", color);
});
// Respond to dynamic width and height.
// "box" is a special property set by chiasm-layout.
my.when("box", function (box) {
// Set the size of the background rectangle.
rect
.attr("width", box.width)
.attr("height", box.height);
});
// Set up the rectangle so that when you click on it, it changes color.
rect.on("click", function (){
my.color = randomColor();
});
// Generates a random color.
function randomColor(){
return "rgb(" + rand() + "," + rand() + "," + rand() + ")";
}
// Generates a random integer between 0 and 255.
function rand(){
return Math.floor(Math.random() * 256)
};
return my;
