I am working on a data visualization project and I have used the Chart.js library for drawing and now I need to export the charts in pdf and png format, what is the best way for me to do it correctly? Thanks for helping my friends ...
If you want to create a feature to allow a user to download the created charts into a image, you can use the 'toDataURL()' function, and specify the canvas of each chart.
To download a canvas as a pdf you can use the jsPDF library, using the above function to retrieve the canvas and then specifying the dimensions.
I may be wrong but I believe you need to create the charts and display on a web page before converting them to an image/pdf. Hope this helps!

How do you export multiple d3 charts to powerpoint? I have created a d3 radar, indicator and bar chart and now I want to have a download button that will allow me to download them as a powerpoint.
I've done this two ways.
The first is to use SVG Crowbar: https://nytimes.github.io/svg-crowbar/
Save it as an SVG and then place the SVG file in your powerpoint like any other image.
The second, kind of janky, way to do it is: Print -> Save as PDF -> convert pdf to svg or jpeg.

I've tried the getImageURI() method, but it only works for core charts.
