• Commented on Data Science and Perl
  Just saw this today. I am the author of Chart::GGPlot and Alt::Data::Frame::ButMore, I know Perl/Python/R quite well, so I might have a say here. I actually had a similar question in my mind, given that Perl already has PDL which...

• Commented on Data analysis and visualization in Perl
  IMO both a Perl/XS graphics backend and the plotlyjs backend have their merits: a Perl/XS backend would be performant in terms of exporting static images, while the plotlyjs backend best suites a web-based environment like Jupyter Notebook. At this stage...
• Commented on Data analysis and visualization in Perl
  Cairo itself relatively low level. In R's implementaion there are multiple layers between the high level of ggplot2 and R's base graphics api, the latter is similar to Cairo. There are quite a lot implementation details there. For someone familiar...
• Commented on Data analysis and visualization in Perl
  Thanks for your comments. 1. Yes I also feel there are too many dependencies. I will try to reduce some of them. On the other hand, compared to Python and R, Perl's CPAN distributions are generally of smaller granularity. 2....

  I guess you actually meant png? You can do it like $p->save("foo.png"). It requires you installplotly-orca, to be precise, its "orca" command findable via PATH env var. If you don't have it, ideally the error message would tell you to...

  Thank you for your comment.

  I install Chart::GGPlot into my CentOS server.

  And I run example program in this entry.

  I write frank comments to improve user experience.

  1. Hope installation more fast.

  When I install Chart::GGPlot, 155 distribution is installed.

  I feel installation time is too long.

  2. Hope Chart creating more fast.

  I run this example. I wait over 30 hours.

  In R language, Chart creating time is much fast.

  3. Chart::GGPlot depend on JavaScript library.

  When I read blog entry at first, I thin…

  Sorry 30 seconds.

  Is it difficult to write point, line, color, text from data frame by Cairo?

• Yuki Kimoto commented on Data analysis and visualization in Perl

  I think one of Perl lacks is Perl/XS graphic library which can create 2D/3D chart easily.

  If installation become easy and perfomrance of chart creating is improved as same as R language, it become more attractive for me.
