scatterplot.render bug

tfjs-vis ver @lastest (1.4.0)

chrome ver 83.0.4103.97

i’m running the demo code in the chrome, the console print 'Cannot read property ‘length’ of undefined ’

the demo code at ‘https://js.tensorflow.org/api_vis/1.4.0/#render.scatterplot’ is:

import * as tfvis from '@tensorflow/tfjs-vis'; // this is my import

const series1 = Array(100).fill(0)
   .map(y => Math.random() * 100 - (Math.random() * 50))
   .map((y, x) => ({ x, y, }));

const series2 = Array(100).fill(0)
   .map(y => Math.random() * 100 - (Math.random() * 150))
   .map((y, x) => ({ x, y, }));

const series = ['First', 'Second'];
const data = { values: [series1, series2], series }

const surface = { name: 'Scatterplot', tab: 'Charts' };
tfvis.render.scatterplot(surface, data);

here is the error message print on console:

Uncaught (in promise) TypeError: Cannot read property ‘length’ of undefined at expression (expression.js:6) at Object.operator (expression.js:25) at Context.operatorExpression (context.js:147) at Context.parseOperator (operator.js:12) at dataflow.js:24 at Array.forEach (<anonymous>) at Context._default [as parse] (dataflow.js:24) at _default (runtime.js:6) at new View (View.js:76) at Object.<anonymous> (embed.ts:276)

i think isn’t fjs-vis version not match it’s dependencies version ?

sorry for my broken english…

I had cleared both, whether I use npm or yarn to install, the error still appears
