The Iris Dataset

This is the "Iris" dataset. Originally published at UCI Machine Learning Repository: Iris Data Set, this small dataset from 1936 is often used for testing out machine learning algorithms and visualizations (for example, Scatter Plot). Each row of the table represents an iris flower, including its species and dimensions of its botanical parts, sepal and petal, in centimeters.

The HTML page provides the basic code required to load the data and display it on the page (as JSON) using D3.js.

For a more up to date code example with React & D3, see (VizHub: Stylized Scatter Plot)[https://vizhub.com/curran/3d631093c2334030a6b27fa979bb4a0d?edit=files&file=index.js].

How to serve a custom HTTPS domain on GitHub Pages with CloudFlare: *FREE*, secure and performant by default

Instructions

CloudFlare is an awesome reverse cache proxy and CDN that provides DNS, free HTTPS (TLS) support, best-in-class performance settings (gzip, SDCH, HTTP/2, sane Cache-Control and E-Tag headers, etc.), minification, etc.

  1. Make sure you have registered a domain name.
  2. Sign up for CloudFlare and create an account for your domain.
  3. In your domain registrar's admin panel, point the nameservers to CloudFlare's (refer to this awesome list of links for instructions for various registrars).
  4. From the CloudFlare settings for that domain, enable HTTPS/SSL and set up a Page Rule to force HTTPS redirects. (If you want to get fancy, you can also enable automatic minification for text-based assets [HTML/CSS/JS/SVG/etc.], which is a pretty cool feature if you don't want already have a build step for minification.)
  5. If you

go fmt

あなたのコードに gofmt を走らせると、自動的に機械的に直すことのできるスタイルの大部分を修正してくれます。 世にあるGolang コードのほとんどすべてが gofmt を使っています。 この文章の残りは機械的に直すことのできないポイントについて解説します。

代わりに goimports を使う手段もあります。
