npm install d3-state-visualizer
import d3 from 'd3';
import d3tooltip from 'd3tooltip';
const DOMNode = document.getElementById('chart');
const root = d3.select(DOMNode);
const vis = root.append('svg');
let options = {
offset: {left: 30, top: 10}
};
vis.selectAll('circle').data(someData).enter()
.append('circle')
.attr('r', 10)
.call(
d3tooltip(d3, 'tooltipClassName', options)
.text((d, i) => toStringOrHtml(d))
.attr({ 'class': 'anotherClassName' })
.style({ 'min-width': '50px', 'border-radius: 5px' })
)
.on({
mouseover(d, i) {
