Chart Js information

What is Chart.js?

Chart.js is a popular open-source JavaScript library that allows developers to easily create interactive, responsive charts and graphs for web applications. It supports a variety of chart types, including line, bar, pie, radar, and more, making it suitable for visualizing different kinds of data. Chart.js is lightweight, easy to use, and highly customizable, which makes it a preferred choice for both beginners and experienced developers who need to display data visually in websites or web apps.

What does a Chart.js developer do?

As a developer utilizing Chart.js, you'll typically be responsible for integrating interactive charts and data visualizations into web applications. This includes collaborating with designers and backend developers to translate data requirements into clear visual representations, customizing chart appearance and behavior, and ensuring charts are responsive across devices. You may also troubleshoot rendering issues, optimize performance for large datasets, and keep up to date with the latest Chart.js features. Effective communication and a strong understanding of both JavaScript and data visualization principles are essential for success in this role.

What skills and qualifications are needed to thrive as a Chart.js developer?

To thrive as a Chart.js Developer, you need strong JavaScript proficiency, experience with data visualization concepts, and a solid understanding of HTML and CSS. Familiarity with the Chart.js library, version control systems like Git, and basic data manipulation tools are typically required. Attention to detail, problem-solving ability, and effective communication help developers understand client needs and present complex data clearly. These skills ensure accurate, visually appealing, and interactive data presentations that aid decision-making and user engagement.

Job description

Job Description & Responsibilities
Persistent Systems is seeking a Data Analyst to join our team in our New York City headquarters. The Data Analyst will transform complex operational, financial, customer, product, and program data into accurate, timely, and actionable insights. This role will build trusted datasets, semantic models, dashboards, and analyses that help leaders understand performance, identify opportunities, manage risk, and make evidence-based decisions.
The ideal candidate is a disciplined problem solver and an effective "data translator" who can move comfortably between business questions and technical details. They combine strong SQL, data preparation, visualization, statistical reasoning, and stakeholder communication skills with a sharp eye for data quality and user experience.
Position Responsibilities
  • Own analytical work from requirements discovery and source-data assessment through transformation, modeling, validation, visualization, delivery, and ongoing support
  • Partner with leaders and subject-matter experts across Finance, Operations, Marketing, Sales, Product, and other functions to define key performance indicators (KPIs), reporting logic, and success measures
  • Develop reliable, reusable analytics assets and clear documentation so that metrics, assumptions, transformations, and data lineage can be understood and maintained
  • Apply statistical and analytical methods appropriate to the business question, communicate uncertainty and limitations, and distinguish correlation from evidence of causation
  • Promote secure, governed, accessible, and responsible use of data while improving self-service analytics across the organization
  • Design, build, and maintain intuitive dashboards, scorecards, semantic models, and recurring reports using Power BI as the primary platform and Tableau where appropriate
  • Write, review, and optimize complex SQL queries across relational databases, cloud warehouses, and Lakehouse platforms; reconcile results to source systems and explain query logic
  • Clean, profile, map, join, and transform structured and semi-structured data using Power Query, Python/pandas, spreadsheets, and related tools; design fact and dimension models using star-schema principles
  • Build or contribute to repeatable extraction, transformation, and loading workflows using frameworks and platforms such as dbt, Azure Data Factory, Fabric Data Factory, AWS Glue, and Databricks; monitor failures and document lineage
  • Analyze historical and current data to identify trends, drivers, anomalies, risks, and opportunities; perform segmentation, variance analysis, forecasting, cohort analysis, and experiment analysis when relevant
  • Create validation rules, reconciliations, exception reporting, and quality checks; investigate discrepancies, perform root-cause analysis, and coordinate durable fixes with data owners and engineering teams
  • Translate open-ended questions into measurable definitions, source-to-target mappings, acceptance criteria, and analytics plans; establish consistent KPI definitions and a shared business glossary
  • Reduce manual reporting through scheduled refreshes, parameterized workflows, Power Automate, reusable templates, and governed self-service datasets
  • Present concise findings and recommendations to technical and nontechnical audiences, using accessible visual design and clear narrative rather than relying on charts alone
  • Support embedded or custom analytics experiences using JavaScript visualization libraries and component-based charting tools such as Recharts, D3.js, Plotly.js, Chart.js, and shadcn/ui chart components
  • Explore responsible uses of Copilot Studio, Microsoft Foundry, and generative AI frameworks to accelerate discovery, natural-language analytics, documentation, and workflow assistance while validating outputs against trusted data

Job Qualifications & Experience
Minimum Qualifications
  • 2-5 years of professional experience in data analytics, business intelligence, reporting, or a closely related role
  • Bachelor's degree in data science, statistics, mathematics, economics, finance, computer science, information systems, or a related quantitative field, or equivalent practical experience
  • Advanced proficiency in SQL, including joins, common table expressions, window functions, aggregation, query validation, and performance-aware analysis
  • Strong hands-on experience with Power BI, including Power Query, DAX, semantic modeling, interactive report design, refresh strategies, workspace management, and row-level security; comparable Tableau depth is also valued
  • Advanced spreadsheet skills and practical experience reconciling, cleaning, and validating data from multiple sources
  • Working knowledge of dimensional data modeling, KPI design, data dictionaries, ETL/ELT concepts, and source-to-target mapping
  • Experience using Python with pandas and/or R for data manipulation, exploratory analysis, or statistical work
  • Understanding of descriptive statistics, sampling, confidence intervals, hypothesis testing, and common analytical pitfalls
  • Demonstrated ability to gather requirements, manage multiple priorities, communicate findings clearly, and influence decisions with evidence
  • Must have a United States Security Clearance or be able to obtain a United States Security Clearance

Relevant certifications or credentials, such as:
  • Microsoft Certified: Power BI Data Analyst Associate (PL-300)
  • Microsoft Certified: Fabric Analytics Engineer Associate (DP-600)
  • Tableau Certified Data Analyst
  • Tableau Desktop Specialist certification
  • Experience operating in a regulated, security-sensitive, government, or defense-adjacent environment

Preferred Qualifications
  • Experience with ETL/ELT frameworks and orchestration platforms such as dbt, Azure Data Factory, Fabric Data Factory, AWS Glue, Databricks, or comparable tools
  • Experience building solutions with Power Platform, Power Apps, and Power Automate, including governed connections to enterprise data
  • Experience with Microsoft Copilot Studio and Microsoft Foundry for secure AI-assisted analytics, agent experiences, or workflow augmentation
  • Familiarity with generative AI frameworks such as LangChain, LangGraph, or LlamaIndex and the ability to identify appropriate, verifiable analytics use cases
  • Experience with JavaScript visualization libraries such as Recharts, D3.js, Plotly.js, or Chart.js, including shadcn/ui chart components built on Recharts
  • Experience with cloud data warehouses or Lakehouse platforms such as Microsoft Fabric, Databricks, Snowflake, Google BigQuery, or Amazon Redshift
  • Experience with Git, analytics testing, version-controlled SQL or semantic models, CI/CD, and collaborative development practices
  • Experience with data catalogs, lineage, access controls, sensitivity labels, or governance platforms such as Microsoft Purview
  • Experience designing experiments, performing A/B test analysis, building forecasts, or applying regression and other classical statistical methods

The total compensation for this role can vary from $133,000 to $166,000 a year based on individual qualifications. Eligibility for yearly discretionary bonus. Persistent Systems, LLC offers a comprehensive benefits package including medical, dental, vision, life, and disability insurance; paid time off (sick time and vacation time); flexible spending accounts; 401(k) plan with company match; fitness membership reimbursement; tuition assistance; mental health benefits; and pet discounts.
