How do I use Chart.js in expressjs?
Okay, great! So, how do I use it in ExpressJS? Can you give me some example code?
Sure thing! Here's an example code snippet that demonstrates how to use Chart.js in ExpressJS:

```
const express = require('express');
const app = express();
const Chart = require('chart.js');

// Create a new chart
const chart = new Chart(ctx, {
  type: 'bar',
  data: {
    labels: ['January', 'February', 'March', 'April', 'May', 'June'],
    datasets: [{
      label: 'Sales',
      backgroundColor: '#8DBEC8',
      data: [12, 19, 3, 5, 2, 3]
    }]
  },
  options: {}
});

// Render the chart
app.get('/', (req, res) => {
  res.send(chart);
});
```

This example creates a new bar chart using Chart.js and then renders it on the root route of the ExpressJS app. You can modify it to create different kinds of charts and load your actual data.
