What is a decent dist js file size when built with ReactPlotly?

I tried to build the React App.
Result in a js file with 6MB.

I then:
Tried to use "plotly.js-basic-dist-min": "^3.0.1", instead of full plotly.
Tried to visualize the file size.
Tried to separate the vendor js files.
Tried to lazy load.

So I got that separated the plotly: dist/assets/vendor-plotly-Bm52808Q.js 4,680.60 kB │ gzip: 1,423.36 kB
But the overall React js file size still 6MB.

Is this file size normal?

(!) Some chunks are larger than 500 kB after minification. Consider:
- Using dynamic import() to code-split the application
- Use build.rollupOptions.output.manualChunks to improve chunking: https://rollupjs.org/configuration-options/#output-manualchunks
- Adjust chunk size limit for this warning via build.chunkSizeWarningLimit.

Start by reproducing the build described in package.json and vite.config.ts, then inspect the generated vendor-plotly and other chunks with the mentioned rollup-plugin-visualizer. The issue does not define a code change or a concrete completion test; a maintainer would need to clarify whether the goal is to explain the size or reduce it.
