I have the same problem, I can't finish installing it on a Drupal 11.1.3, the error text it gives me is the following:
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires drupal/charts_echarts ^1.0 -> satisfiable by drupal/charts_echarts[1.0.0].
- drupal/charts_echarts 1.0.0 requires apache/echarts 5.3.2 -> could not be found in any version, there may be a typo in the package name.
Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
see for more details.
- It's a private package and you forgot to add a custom repository to find it
Read for further common problems.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
exit status 2
Composer [require drupal/charts_echarts:^1.0] failed, composer command failed: exit status 2. stderr=
