D3.js
- データビジュアリゼーションライブラリ
- チャートや図などを簡単にかけるライブラリ
d3-interpolate
- 2つの値の間を補完するライブラリ
- 数値の補完から色の補完までおこなう
- ソースを見る感じ、色差は厳密に考慮されていない?
- 改善の余地ありか
d3-scale
- こちらも同様に補完してくれる
- 色差計算の必要あり?
xcrun: error: active developer path ("/Applications/Xcode.app/Contents/Developer") does not exist
brew doctor
結果(現れたWarningたち抜粋)
Warning: You have the following deprecated, official taps tapped: Homebrew/homebrew-binary Untap them with `brew untap`. Warning: "config" scripts exist outside your system or Homebrew directories. `./configure` scripts often look for *-config scripts to determine if software packages are installed, and which additional flags to use when compiling and linking. Warning: No developer tools installed. Install the Command Line Tools: xcode-select --install Warning: Unbrewed header files were found in /usr/local/include. If you didn't put them there on purpose they could cause problems when building Homebrew formulae, and may need to be deleted. Warning: You have unlinked kegs in your Cellar. Leaving kegs unlinked can lead to build-trouble and cause brews that depend on those kegs to fail to run properly once built. Run `brew link` on these: ghostscript heroku python xcrun: error: active developer path ("/Applications/Xcode.app/Contents/Developer") does not exist Use `sudo xcode-select --switch path/to/Xcode.app` to specify the Xcode that you wish to use for command line developer tools, or use `xcode-select --install` to install the standalone command line developer tools. See `man xcode-select` for more details. Warning: Homebrew's sbin was not found in your PATH but you have installed formulae that put executables in /usr/local/sbin. Consider setting the PATH for example like so: echo 'export PATH="/usr/local/sbin:$PATH"' >> ~/.bash_profile Warning: Broken symlinks were found. Remove them with `brew cleanup`:
なるほどわからん
とりあえず言われたとおりにコマンドを打ちこんでみる
xcode-select --install
するとコマンドラインデベロッパーツールなるやつをインスコしろとの指示が...
(とりあえずここまで)
色差・色空間について調べたので自分なりにまとめてみた.
全然わからん...
