Hello World example

Create an element to hold the table

<div id="mykmeans"></div>

Turn the div element into a d3 scatter chart with some simple javascript

var mykmeans = kmeansjs.kmeans();
mykmeans.init(document.getElementById("mykmeans"), {
    selectedDataSet: [
    {age: 37, year_of_operation: 63, positive_axillary_nodes: 0, survival_status: 1},
    {age: 43, year_of_operation: 58, positive_axillary_nodes: 52, survival_status: 2},
    {age: 43, year_of_operation: 59, positive_axillary_nodes: 2, survival_status: 2},
    {age: 43, year_of_operation: 63, positive_axillary_nodes: 14, survival_status: 1},
    {age: 43, year_of_operation: 64, positive_axillary_nodes: 2, survival_status: 1},
    {age: 46, year_of_operation: 65, positive_axillary_nodes: 20, survival_status: 2},
    {age: 48, year_of_operation: 66, positive_axillary_nodes: 0, survival_status: 1},
    {age: 50, year_of_operation: 61, positive_axillary_nodes: 0, survival_status: 1},
    {age: 54, year_of_operation: 62, positive_axillary_nodes: 0, survival_status: 1},
    {age: 58, year_of_operation: 61, positive_axillary_nodes: 2, survival_status: 1}
    ], 
    selectedColumns: ["age", "year_of_operation"]
});

Work with the chart table

Include the libraries

<script src="https://d3js.org/d3.v4.min.js"></script>
<script src="../dist/kmeansjs.min.js"></script>
<script src="../dist/charttable.min.js"></script>

<link rel="stylesheet" href="../dist/charttable.min.css"></link>

Create div elements to hold the table

<div id="mytable"></div>
<div id="mykmeans"></div>

Work with chart table

const mytable = charttable.table();
const mykmeans = kmeansjs.kmeans();
const tol_vibrant = ["#EE7733", "#0077BB", "#33BBEE", "#EE3377", "#CC3311", "#009988"];
mytable.initTbl(document.getElementById("mytable"), {
    colors: tol_vibrant,
    minSelectedRow2Show: 4,
    minSelectedCol2Show: 2,
    height: 540,
    onSelect: function(data) {
    mykmeans.init(document.getElementById("mykmeans"), {
        selectedDataSet: data.selectedRows, 
        selectedColumns: data.selectedColumns
    });
    }
});

mytable.showDataset([
    {age: 30, year_of_operation: 65, positive_axillary_nodes: 0, survival_status: 1},
    {age: 38, year_of_operation: 66, positive_axillary_nodes: 0, survival_status: 1},
    {age: 42, year_of_operation: 59, positive_axillary_nodes: 0, survival_status: 2},
    {age: 49, year_of_operation: 63, positive_axillary_nodes: 0, survival_status: 2},
    {age: 49, year_of_operation: 61, positive_axillary_nodes: 0, survival_status: 1},
    {age: 55, year_of_operation: 66, positive_axillary_nodes: 18, survival_status: 1},
    {age: 56, year_of_operation: 60, positive_axillary_nodes: 0, survival_status: 1},
    {age: 61, year_of_operation: 65, positive_axillary_nodes: 0, survival_status: 2},
    {age: 61, year_of_operation: 59, positive_axillary_nodes: 0, survival_status: 1},
    {age: 64, year_of_operation: 66, positive_axillary_nodes: 0, survival_status: 1}
]);

• use webpack to build
• publish to npm and CDN - UNPKG
• remove charttable.min.js once we can publish to npm
