CodeChef is a not-for-profit educational initiative started by Directi more than a decade ago. We started with a dream of seeing an Indian team winning a gold medal at the ACM ICPC World Finals. In its quest for the same, CodeChef has built a self-driven community of the world's best programmers. Today more than 1.3 million competitive programmers from 180+ countries learn from CodeChef. CodeChef has been hosting monthly programming contests regularly for 10 years now. Its platform has assessed 92 million+ code submissions to date, and over 30000 organizations are being impacted by CodeCheffers worldwide. It also organizes SnackDown - one of the world's largest global programming competition whose last edition drew participation from 140+ countries. Since 2017, CodeChef has started providing India's only industry-ready certification in Data Structures and Algorithms, and 1800+ programmers have been certified under the same.
Graphviz CodechefBased on our record, Graphviz seems to be a lot more popular than Codechef. While we know about 80 links to Graphviz, we've tracked only 7 mentions of Codechef.

Conventions exist but they're mostly crap. Along the KISS principle, boxed elements with connecting nodes are the best (most universally understood). In mathematical terms, this is an 'undirected graph', a 'directed graph' is the same but with directionality on the links between nodes. The standard toolkit for defining these in software is https://graphviz.org/ If you need to show the interaction between elements... - Source: Hacker News / about 2 months ago
Thoughtful post, thanks. However, this tripped me up: "our GPU graph viz server" -- I couldn't understand how you a) scale graphviz[1] on a GPU and b) make money hosting graphviz. Quick read of your web site cleared that up :) [1] https://graphviz.org/. - Source: Hacker News / 5 months ago
Tracing flows: breakdown complex UDP/TCP ECMP traces into individual flows (i.e. Common network path); render a chart of flows in GraphViz DOT format (example). Source: 6 months ago
It has the look of graphviz about it, which is an excellent tool. Often helpful in debugging anything related to graphs. https://graphviz.org/. - Source: Hacker News / 9 months ago
If you are talking about making visualisations for other people it would depend if you want to make them interactive, static, or a mix of the two. I’m not really sure what to recommend given I don’t know - but here are a few places to start: - Python tutor - manim - processing - graphviz - simple but good - draw.io. Source: about 1 year ago
Have you heard of codeforces.com, atcoder.jp, codechef.com, etc? Source: 6 months ago
Leetcode is good to learn basic algorithms because problem statements are usually straightforward. Competitive programming has much wider range of problems. Most popular sites for cp are codeforces.com , atcoder.jp, codechef.com . Source: 6 months ago
Learn Java with hands-on experience. I personally used codingbat.com a lot, but I've heard good things about codechef.com, which appears to even have a competitive option. Source: over 1 year ago
For practicing algorithms, use any of the freely available websites like https://hackerrank.com https://codechef.com https://projecteuler.net A structured set of practice problems are available at https://www.interviewbit.com/courses/programming/ Avoid https://geeksforgeeks.org because it has a ton of material but very poor quality control.

These all have sample problems to solve Hackerrank.com edabit.com codewars.com codechef.com and there are tons more. Best of luck to you. I am at about the same level myself. I really like these sites. Source: over 2 years ago
