What Hacker News says
5 sourcesi could not find a simple/minimal d3 timeseries example. these are huge and very explicit:
https://bl.ocks.org/d3netxer/10a28b7aee406f4e7fce
https://bl.ocks.org/robyngit/89327a78e22d138cff19c6de7288c1c...
if you know d3 well enough to faithfully match what the benchmarks do, then please submit a PR. or at least point me to a minimal demo.
maybe i can do one using c3.js, which is d3-based: https://c3js.org/samples/timeseries.html
this demo uses SVG, so it will very likely be poor. i don't know if there's an option to use a d3 canvas-based backend?
it does not appear so: https://github.com/c3js/c3/pull/1436#issuecomment-302930456
In Show HN: uPlot.js – An exceptionally fast, tiny time series chartC3.js[0] has a built in image exporter[1] you can use from the command line if you want to generate chart images programatically. I use something similar that I wrote just before this became part of C3 to generate the chart and upload it to S3. Then my email links to that image. Works very nicely!

In Ask HN: What tools do you use to build HTML emails?Great, but I dislike the combined JS filesize. 267kb is simply still too big for mobile websites, given that it is only a part of a website. It seems to consume a bit too much memory for my iPad2, the first time I saw a blank demo; had to re-open Safari. (combined: c3 is 120kb and d3 is 147kb) c3.min:
https://github.com/masayuki0812/c3/blob/master/c3.min.js , d3.min: https://github.com/mbostock/d3/blob/master/d3.min.js
A charts library that has no dependecies (no d3, no jquery, etc), has a filesize of less than 100kb and still looks great and offers useful features would be awesome. SVG vs. Canvas2D is another hot topic.
In C3.js: D3-based reusable chart libraryI like C3, but I discovered it has some major performance issues with thousands of data points a couple months back. It has something to do with the pie chart rendering code: https://github.com/masayuki0812/c3/issues/172#issuecomment-4...
I've been evaluating HighCharts, Vega, Rickshaw, NVD3, C3, but the one I've been impressed with in terms of performance thus far is Epoch: http://fastly.github.io/epoch/
